Question

A hammer of mass 1500g moving at 75m/s, strikes a nail. The nail stops the hammer in a

very short time of 0.1s. What is the force of the nail on the hammer? ​

Answer 1

ACCORDING TO 2ND LAW OF MOTION

$f = \frac{dp}{dt}$

$f = \frac{1.5 \times (0 - 75)}{0.1}$

$f = - 15 \times 75$

$f = - 1125 \: newton$
