Question

A lead bullet of mass 20 g, travelling with a velocity of 350 m s-1, comes to rest after penetrating 40 cm in a still target. Find (i)the resistive force offered by the target (ii)the retardation caused by it.

Answer 1

the resistive force offered by the target and (ii) the ... s= 40cm = . 4m ... a = -153125 m/ s^{2} F = ma m = 20 g = .02 kg ... Physics; 5 points; 1 ...
