. A hammer of mass 500 g, moving at 50 m s-1, strikes a nail.
The nail stops the hammer in a very short time of 0.01 s. What is the force of the nail on the hammer?
Answer: Given, mass of the hammer (m) = 500g = 0.5kg
Initial velocity of the hammer (u) = 50 m/s
Terminal velocity of the hammer (v) = 0 (the hammer is stopped and reaches a position of rest).
Time period (t) = 0.01s
