Using second law of motion, derive the relation between force and acceleration. A bullet of `10g` strikes a sand-bag at a speed of `10^(3)ms^(-1)` and gets embedded after travelling `5cm`.Calculate (i) the resistive force exerted by the sand on the bullet (ii) the time taken by the bullet to come to rest.
