A bullet of mass 0.02 kg is fired from a rifle. The bullet takes 0.02s to move through the barrel and leaves with a velocity of 200 ms 1. What is the acceleration acting on the bullet?

Initial velocity of the bullet = 0 ms-1

Final velocity of the bullet = 200 ms-1

Time to travel = 0.02 s

Using v= u + at

a= (v-u)/t = (200-0)/0.02 = 10000 ms^-2
