What is the initial velocity of a ball thrown upward?
A ball is thrown upward with an initial velocity of 20 m/s. How long will the ball take to reach its maximum height? - Quora A ball is thrown upward with an initial velocity of 20 m/s. How long will the ball take to reach its maximum height? 8 clever moves when you have $1,000 in the bank.
How do you find the initial velocity from acceleration and distance?
If you are given the final velocity, acceleration, and distance, you can use the following equation: Initial velocity: Vi = √ [Vf2 - (2 * a * d)] Understand what each symbol stands for. Vi stands for “initial velocity”
How do you calculate time taken to throw a vertically thrown object?
So (from equation ii and vi) for a vertically thrown object the total time taken for its upward and downward movements = t + T=2v1/g ………. (vii) 1) The maximum height reached by it would be = v12/2g= (98 x98 )/ (2 x 9.8) meter = 490 meter. 2) The time taken to reach the highest point = v1/g = 98 / 9.8 second = 10 second
What is the acceleration of the ball due to gravity?
The acceleration of the ball would be equal to the acceleration due to gravity caused by gravitational pull or force exerted by the earth on the ball. Its value is approximately 9.8 m/s^2 and its direction would be downwards towards the center of the earth.

What is the velocity of the ball after 2 seconds?
19.6 m/sFor example, if a projectile is moving upwards with a velocity of 39.2 m/s at 0 seconds, then its velocity will be 29.4 m/s after 1 second, 19.6 m/s after 2 seconds, 9.8 m/s after 3 seconds, and 0 m/s after 4 seconds.
What is the formula for finding initial velocity?
How do you find initial velocity? Work out which of the displacement (S), final velocity (V), acceleration (A) and time (T) you have to solve for initial velocity (U). If you have V, A and T, use U = V - AT. If you have S, V and T, use U = 2(S/T) - V.
What is the initial velocity of a ball thrown?
Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.
How do you find initial velocity and final velocity?
Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth's gravitational force as the acceleration rate of an object.
How do you find initial velocity with initial position?
If you know values for the distance, time, and acceleration, you can use the following equation:Initial velocity: Vi = (d / t) - [(a * t) / 2]Understand what each symbol stands for. Vi stands for "initial velocity" d stands for "distance" a stands for "acceleration" t stands for "time"
What is the initial velocity?
Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts. They are four initial velocity formulas: (1) If time, acceleration and final velocity are provided, the initial velocity is articulated as. u = v – at.

What is the acceleration of the ball after 1 second?
Gravity causes an object to fall toward the ground at a faster and faster velocity the longer the object falls. In fact, its velocity increases by 9.8 m/s2, so by 1 second after an object starts falling, its velocity is 9.8 m/s.
What is the initial velocity of the object thrown upward?
If an object is merely dropped (as opposed to being thrown) from an elevated height, then the initial velocity of the object is 0 m/s. If an object is projected upwards in a perfectly vertical direction, then it will slow down as it rises upward.
What does it mean when an object travels with an initial velocity?
If the object is already traveling with an initial velocity, you have to take it into account, too: You can immediately see that the object distance traveled is proportional to the fall time squared. It means that with each second, the falling body travels a substantially larger distance than before.
How to calculate free fall acceleration?
How do you find free fall acceleration of a planet? 1 Estimate the total mass of the planet in kilograms. 2 Estimate the radius of the planet, from its center to its surface, in meters. 3 Divide the total mass by radius squared. 4 Multiply the result by the universal Gravitational constant, 6.67×10 -11 N·m 2 ·kg -2. 5 The result is the gravitational force of the planet, which is also its free fall acceleration.
What is the only force that moves an object in free fall?
In free fall, an object moves under the influence of gravitational force only. The only acceleration is the acceleration of gravity g. No other force, including air resistance, is acting on such an object. Interestingly, an object in free fall doesn't necessarily need to be falling (that is, moving downwards).
How to determine the weight of an object in free fall?
An object in free fall will still have a weight, governed by the equation W = mg, where W is the object’s weight, m is the object’s mass, and g is the acceleration due to gravity. Weight, however, does not affect an object's free falling speed.
Why does the Moon move in a tangential orbit?
It's because Moon's speed is not directed towards Earth, but tangentially to its orbit. Since the Moon is moving along an elliptic orbit with the first cosmic velocity, its motion generates a centrifugal force, equal and opposite to the force of gravity.
Does the distance depend on the mass of the falling object?
Another interesting fact is that according to the free fall formula, the distance does not depend on the mass of the falling object. If you drop a feather and a brick, they will hit the ground at the same time...
Is it possible to fall in a vacuum?
In fact, a real free fall is only possible in a vacuum. Nevertheless, this is as close to the actual experience as you can get on Earth 😉. One of the most extreme examples of an almost-scientifically-correct free fall is the jump of Dr. Alan Eustace, Google's VP of Knowledge, in 2014.
What happens when a ball is thrown vertically upward?
When a ball is thrown vertically upward it starts its vertical motion with an initial velocity. As it moves upwards vertically its velocity reduces gradually under the influence of earth’s gravity working towards the opposite direction of the ball’s motion. In other words, during upward movement, the ball is moving with retardation.
What is the value of g in SI?
As this acceleration due to gravity (g) is working opposite to the upward velocity we have to use a negative sign in the formula below, used for the upward movement of the ball.#N#We know the value of g in SI is 9.8 m/second square.
Is acceleration due to gravity?
And Yes. As said above, this acceleration is nothing but the acceleration due to gravity caused by gravitational pull or force exerted by the earth on the ball. Its value is generally taken as 9.8 m/s^2. See here how acceleration due to gravity varies with height and depth wrt the surface of the earth.
How to solve physics problems?
In order to solve any physics problem you must know which equation to use. Writing down all of the known information is the first step to finding the right equation. If you know values for the distance, time, and acceleration, you can use the following equation:
What is velocity in physics?
Velocity is a function of time and defined by both a magnitude and a direction. Often in physics problems, you will need to calculate the initial velocity (speed and direction) at which an object in question began to travel. There are multiple equations that can be used to determine initial velocity.
