Question

a mechanic strikes a nail with a hammer of mass 500 g moving with a velocity of 20 metre per second the hammer comes to rest in 0.02 s after striking the nail. Calculate the force exerted by the nail on the hammer​

Answer 1

Answer:

5000N

Explanation:

Given,

mass= 500g, velocity=20m/s, time=0.02s

we know,

Force= mass of an object. acceleration

As per the question,

we have, acceleration= change in velocity/ time taken

= 20/0.02

= 1000m/s

therefore, force= 500 g . 1000 m/s

= 5000N
