A squash ball typically rebounds from a surface with 25%
Chapter , Problem 107(choose chapter or problem)
A squash ball typically rebounds from a surface with 25% of the speed with which it initially struck the surface. Suppose a squash ball is served in a shallow trajectory, from a height above the ground of 45 cm, at a launch angle of 6.0 degrees above the horizontal, and at a distance of 12 m from the front wall. (a) If it strikes the front wall exactly at the top of its parabolic trajectory, determine how high above the floor the ball strikes the wall. (b) How far horizontally from the wall does it strike the floor, after rebounding? (Ignore any effects due to air resistance.)
