Question

Pls answer this ques its very very urgent


A hammer of mass 500 gm moving at a speed of 50m/sec , strikes a nail .The nail stop the hammer in a very short time of 0.01 sec. What is the force of the nail on the hammer ?

Answer 1

m=500g
=500/1000
=0.5kg

u=50m/sec

v=0m/sec

t=0.01sec

v=u+at

0=50+0.01×a

-50=0.01×a

-50/0.01=a

-5000=a

=> Retardation=5000m/sec

F=m×a

F=0.5×5000

F=10000N
