Question

A spherical 0.34 kg orange, 2.0 cm in radius, is dropped from the top of a building of height 31 m. After striking the pavement, the shape of the orange is a 0.60 cm thick pancake. Neglect air resistance and assume that the collision is completely inelastic.(a) Estimate how much time the orange took to completely "squish" to a stop? (b) What average force did the pavement exert on the orange during the collision?
