Question

A bullet of mass 50 g moving with an initial velocity of 360 km/h, strikes a wooden block and comes to rest after penetrating a distance 20 mm in it. Calculate (i) initial momentum of the bullet, (ii) final momentum of the bullet (iii) retardation caused by the wooden block, and (iv) resistive force exerted by the wooden block​

Answer 1

Explanation:

1. intial momentum =MU

2. final momentum= MV

3 retardation=negative acceleration

4.force =ma
