Question

A hammer weighing 3 kg moving with velocity 10 metre per second strikes horizontally is the head of a spike and drives it into a block. If the hammer comes into rest in 0.025 seconds find impulse and average driving force on the spike ?

Answer✏️

30 Ns

Initial momentum of the hammer P

i =mu=3×10=30 kg m/s

Final momentum of the hammer P

f =0

Change in momentum of hammer ΔP=P

f −P i=0−30=−30 kg m/s

Impulse acting on the hammer I

hammer=ΔP=−30 Ns

Impulse acting on the spike I

spike =−I hammer =30 N s
