​

Answer 1

Answer:

During free fall:

Acceleration of the boy = Acceleration of mass M = g

Acceleration of mass M w.r.t. boy, a = 0

So, the force exerted by the box on the boy's head = M × a = 0

Yes, the force greatly increases during the period he balances himself after striking the ground because of the weight of the box.
