A boy puts a heav
When the boy jumps from the building, the acceleration of boy as well as the box become g (acceleration due to gravity). Hence the net force is exerted by the earth and none of them exert any contact force.
Yes, the force greatly increases when he strikes on the ground because it becomes impulsive force and the boys head exerts a huge force which reduces the momentum of the box to zero in a very short period of time.
