A theif jumps from top of a building carring a breifcase of 13 kg on his head. Given that weight of theif be 70 kg and height of building be 10 meters. Then find the force that breifcase apply on theif. Take g{ accleration due to gravity = 10 units.

Since the work done is perpendicular to the ground , the work done is zero.If the work done is zero,then either the force is zero or the distance is zero.Since displacement is never zero,the force is zero.
