What angle is the golf ball hit at?
A golf ball is hit at an angle of 45° above the horizontal. What is the acceleration of the golf ball at the highest point in its trajectory? [Neglect friction.] a = m/s2
What is the acceleration of the golf at the maximum height?
The acceleration of the golf at the maximum height is equivalent to acceleration due to gravity = 9.8 m/s². Acceleration is defined as the change in velocity per change in time of motion.
What is the maximum height attained by the ball?
The maximum height attained by the Ball is H= [U sin¶]^2/2g..5). Putting these values of¶, U into 5), H= 19.46 m. AFTER SOLVING YOUR PROBLEM,I HAVE POSTED A PAIR OF VIDEOS WITH THE FIRST ONE PERTAINING TO THE PROBLEM STATEMENT WHILE THE SECOND ONE TO THE SOLUTION.
What is the horizontal acceleration of a projectile?
zeroNothing accelerates a projectile horizontally, so horizontal acceleration is always zero.
What is the acceleration of a ball thrown upward at its highest point?
zeroAnswer: 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.
What is the horizontal velocity of the golf ball?
9.0 meters per secondThe ball has an initial vertical velocity of 9.0 meters per second and an initial horizontal velocity of 9.0 meters per second. The ball reaches its maximum height 0.92 second after its launch. [Neglect air resistance and assume the ball lands at the same height above the ground from which it was launched.]
When the golf ball reaches the maximum height What happens to the vertical velocity?
(c) The velocity in the vertical direction begins to decrease as the object rises. At its highest point, the vertical velocity is zero. As the object falls toward Earth again, the vertical velocity increases again in magnitude but points in the opposite direction to the initial vertical velocity.
How do you find the acceleration?
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction.
What are the velocity and acceleration of the ball at the highest point in its path?
At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth (see figure 1).
What is the velocity of the ball when it hits the ground?
Multiply the time by the acceleration due to gravity to find the velocity when the object hits the ground. If it takes 9.9 seconds for the object to hit the ground, its velocity is (1.01 s)*(9.8 m/s^2), or 9.9 m/s.
What is the horizontal displacement of the golf ball?
KINEMATICS; Golf ball trajectory Seeing as the ball is a projectile motion, we will cover max speed, max height, acceleration, velocity and displacement. Calculations: *Max height (20.116 m), horizontal displacement (128.016 m), angle of elevation (14.6 degrees), max speed (45.555 m/s) and time are all given.
What is the acceleration of the ball all throughout its flight?
TRUE - A projectile has a vertical acceleration of 9.8 m/s/s throughout the entire trajectory. This acceleration value is constant. This means that the vertical velocity changes by the same amount - 9.8 m/s - during each second of its motion.
When a projectile launched at an angle with the horizontal reaches its maximum height then?
The speed of a projectile when it reaches its maximum height is one-half its speed when it is at half its maximum height.
How do you find velocity with maximum height?
h = v 0 y 2 2 g . h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity.
What is the maximum height reached by the golf ball?
The ball will reach a maximum height of 9.31 meters. Known: Up will be considered positive and down will be considered negative a = g = -9.81 m/s2 Vi= 5.6 m/s @ 35° y = -11 m x= ?
What is the angle of a golf ball?
Originally Answered: A golf ball is hit at an angle of 45° to the horizontal and makes a hole in one 180.0 metered away. No air resistance and course is flat. What is the initial speed and maximum height of the ball?
Do both balls have the same displacement?
The ball that was thrown upwards will travel a longer path to get there, but the straight-line distance from the point of release to the point of impact with the ground will be the same as for the other ball. Therefore both balls have an equal displacement (same net distance and overall direction of travel) a.
