A tennis ball is dropped from 1.79 m above the ground. It rebounds to a height of 1.01 m.
part 1 of 3A tennis ball is dropped from 1.79 m above the ground. It rebounds to a height of 1.01 m. With what velocity does it hit the ground? The acceleration of gravity is 9.8 m/s2. (Let down be negative.) Answer in units of m/s. part 2 of 3 With what velocity does it leave the ground? Answer in units of m/s. part 3 of 3 If the tennis ball were in contact with the ground for 0.0126 s. find the acceleration given to the...
