Part 1 A tennis ball is dropped from 1.29 m above the ground . It rebounds to a height of 0.839 m. With what velocity does it hit the ground ? The acceleration of gravity is 1.8 m/s ^ 2 . (Let down be negative .) Answer in units of m/s Part 2 With what velocity does it leave the ground ? Answer in units of m/s
Part 3 If the tennis ball were in contact with the ground for 0.0133 s. find the acceleratio given to the tennis ball by the ground . Answer in units of m/s^ 2
