Question

A bullet of mass 25g is travelling at a speed of 450 m/sec. when it strikes the armour plating of a tank. It bounces back along the same path with a speed of 390 m/sec. (i) Calculate the momentum of the bullet (ii) The time of impact of the bullet is 0.40 s. Calculate the average force that acts on the bullet in this time. (iii) State weather the impact is elastic or inelastic. Explain your answer. (iv) Discuss the principles of conservation of energy and momentum apply to this collision.​
