A hammer of mass 500g, moving at 50m/s, strikes a nail. The nail stops the hammer in a very short time of 0.01s. What is the force of the nail on the hammer?

F = m x a
a = (v-u)/t
F = m x (v-u)/t
Thus, F = 0.5 x (50-0)/0.01
F = 2500 N

- explain the derivation of laws of motion
- A hockey ball of mass 200g travelling at 10m/s is struck by a hockey stick so as to return it along its original path with a velocity at 5m/s.Calculate the change of linear momentum occurred in the motion of the hockey ball by the force applied by the hockey stick.

- Two bodies have mass 10kg and 15kg have identical size. Which has more inertia?
- According to newton's first law of motion an object tends to remain at rest or in uniform motion until and unless and external forces acts on it so suppose a dog is sleeping and then suddenly it wakes up and starts walking so it has come into motion without any external force acting on it how
