1. Using second law of motion, derive the relation between force and acceleration. A bullet of 10
strikes a sand-bag at a speed of 103 ms1 and gets embedded after travelling 5 cm. Calculate
[105 N
(i) the resistance force exerted by the sand on the bullet.
[1045
(ii) the time taken by the bullet to come to rest.
