Problem 7.8: A ball is dropped on a hard floor
Please wait for the animation to completely load.
A ball is dropped on a hard floor as shown in the animation (position is given in meters and time is given in seconds). Assume that the acceleration due to gravity is 9.8 m/s2. Restart.
- What is the speed of the ball the instant before it hits the ground?
- How much energy (in % of original energy) is lost in the collision with the floor?
- What is the coefficient of restitution for the ball?
The coefficient of restitution, for the collision where one object does not move, is the ratio |vf | / |vi|.
