Someone help me with this physics question please? So lost! A bouncy ball is dropped from a height, h, and rebounds off the floor, returning to essentially the same height. During the actual bounce (while it is in contact) the ball is flattened and deformed by amount, y, before returning to its original shape. a) derive an expression for the acceleration, a, while the ball is in contact with the floor. b) use the result to calculate the acceleration if h = 1.50m and y=0.50cm
