Increasing the height from which it is released increases the height to which it rebounds.
39 m\s downward
Yes, they will hit the ground at the same time because while they will have different velocities over all, they will at all times have the same vertical velocity. And its that velocity which determines when they hit the ground.
No. They both hit the ground at the same time, because the VERTICAL component of velocity in both cases is the same.
No. They both hit the ground at the same time. This is because the VERTICAL component of velocity in both cases is the same.
You should start pumping a basketball with air when it rebounds less than half the height where you dropped it from.
1.39 Ns up
it's because of the gravity :)
You can solve this using kinematics: Since you have height: 20m and acceleration being 10 for this question you can easily find the final velocity The initial velocity MUST be 0 since you are dropping it. with that being said Use: V^2= Vi^2 + 2ad
The height to which a dropped ball rebounds is typically significantly greater than the height of the ball. Also, incidentally, the height of the ball usually doesn't change during the event, and remains equal to its original height.
