Question

The hammer mass 500 gm moving at a speed of 50m/s,strikes a nail. The nail stop the hammer in a very short time of 0.01 sec. What is the force of the nail on the hammer questions the answer

Answer 1

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
