Question

A Hamer of mass 500g moving 50ms-1 strikes a nail the nail stop the hammer in a very shoot time 0.01s what is the forces of the nail on the hammer

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
