A ball is dropped from a height of 1 m. if coefficient of restitution between the surface and the ball is 0.6, the ball rebounds to a height of A 0.6 m
Full Answer
What makes a golf ball bounce higher?
The stiffer the ball and the harder the surface, the higher the ball bounces. When a ball hits a hard surface, it sends force to the ground. The ground then returns that force, causing the ball to bounce.
What determines the height at which a ball will bounce?
The height to which a ball will bounce depends on the height from which it is dropped, what the ball is made out of (and if it is inflated, what the pressure is), and what the surface it bounces from is made out of. The radius of the ball doesn't really matter, if you are measuring the height of the ball from the bottom of the ball to the ground.
Which golf ball has the lowest bounce?
The lower bounce ball was the Callaway Chrome Speed - a 4pc Urethane "off market" ball, never actually released by Callaway but discussed quite a bit around here as a sale/closeout ball. Thanks all for the ideas, interesting stuff but true - no real indication of reaction from the club/ball impact speed variables.
How high will the ball reach after the 6th bounce?
"A ball is dropped from a height of 300cm and bounced 270cm, and then again bounced by 243cm, and so on. How high will the ball reach after the 6th bounce?" The heights in three successive bounces = 300 cm, 270 cm, 243 cm which are in a GP as these can be written as 270,270*0.9, 270*0.9² Height after the first bounce = 270cm= 300* 0.9 cm
How high does a golf ball bounce when dropped?
To support their claim, they did a comparison of elasticity using their ball and its major competitor. When dropped from any height onto a hard surface, their ball will rebound 0.8 (80%) of the original height, whereas the competitors ball will have a rebound ratio of only 0.7 (70%).
Does the drop height affect the bounce height of a ball?
The relationship between drop height and bounce height is only linear for small drop heights. Once a ball reaches a certain height, the bounce height will begin to level off because the ball will reach its terminal velocity.
How do you calculate ball bounce?
200 represents the initial height, and (2, 111) represents the second height after the first bounce at 111 cm. We now know that this ball has a 55.5% rebound ratio. We can fill in a table or calculate the height of the ball after each further bounce....Student Exploration.1200130.17082278311 more rows•Oct 14, 2013
Is released from a height of 1 Metre what time it will take to reach the surface of the earth?
What time it will take to reach the surfacethe earth ? Ans:0.45 s.
How is bounce height measured?
Stand 1 meter from the wall. Measure this distance using a meterstick. Bounce each ball toward the wall without using any of your own force. Record the results by measuring the distance from the ground to the paint on the butcher paper.
What determines how high a ball bounces?
When the ball hits the ground, all that kinetic energy has to go somewhere. A lot of it goes back into the ball, giving it more force to pop back up into the air—so the higher the potential energy, the higher the kinetic energy, and the higher the kinetic energy, the higher the bounce!
What is rebound height?
The relationship between the maximum height attained by the ball on a given bounce (which we will call the rebound height) and number of bounces that have occurred since the ball was released is an exponential.
How high a ball will bounce physics?
If the first height is h, the second will be f*h, the third f*f*h, the fourth f*f*f*h, and so on. So if f is 0.9, the first bounce will be 0.9 times as high, the second 0.81 times as high, the third 0.729 times as high (as the original height), and so on.
What is the height of the ball after 3 seconds?
150 feetAfter 3 seconds, the height of the ball is 150 feet.
How long will it take the ball to reach the ground?
That answer depends on the amount of time the balls are in the air. To decide where the balls land, we need to determine how long the balls are in the air. Both balls will take 2 seconds to hit the ground. it was dropped.
What happens to the velocity of a ball as it is dropped off a cliff?
When the ball comes back down to ground level it has exactly the same speed as when it was thrown up, but its velocity is reversed. This is an example of the law of conservation of energy.
What is the energy of a ball?
A ball's gravitational potential energy is proportional to its height. At the bottom, just before the bounce, this energy is now all in the form of kinetic energy . After the bounce, the ball and the ground or floor have absorbed some of that energy and have become warmer and have made a noise.
What is the F of a superball?
For a superball, f may be around 90% (0.9) or perhaps even bigger. For a steel ball on a thick steel plate, f is >0.95. For a properly inflated basketball, f is about 0.75. For a squash ball, f might be less than 0.5 or 0.25 - squash balls are not very bouncy.
Does the radius of a ball matter?
The radius of the ball doesn't really matter , if you are measuring the height of the ball from the bottom of the ball to the ground. A ball's gravitational potential energy is proportional to its height. At the bottom, just before the bounce, this energy is now all in the form of kinetic energy. After the bounce, the ball and ...
How high does a ball bounce?
Werner, Unfortunately there are only two things you will find out about a ball, by bouncing it from a height of about 5 feet . One is, how high it bounces from this height and two, how fast it will come off a putter.
How far does a ball travel without dimples?
The aerodynamics of a ball are extremely important. For example, a ball without dimples will travel about 130 yards compared to an otherwise identical ball with dimples ' launched at the same speed, spin, and launch angle ' which will travel 260 yards. The dimple configuration and the spin rate therefore play a very important role in distance ...
