Answer:

mass of hammer is equal to ,m is 500 grams is 0.5 kg

initial velocity of hammer ,u is 50 m/s

time taken by the nail to stop the hammer,is 0.01

velocity of the hammer (since the hammer finally comes rest) fist newtons 2 and law of motion:

Explanation:

From Newton’s second law of motion:

Force, f = m(v-u) / t

= 0.5(0-50) / 0.01

= -2500 N

The hammer strikes the nail with a force of 2500 N. Hence, from Newton’s third law of motion, the force of the nail on the hammer is equal and opposite, i.e., +2500 N.
