Question

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

Answer 1

Answer:

m = 500g = 0.5 kg

v = 0 m/s

u = 50 m/s

t = 0.01 s

F = m(v-u) / t

F = 0.5 (50-0) / 0.01

F = 0.5 x 50 x 100 / 1

F = 2500 N

Force of nail = 2500 N
