Question

a mechanic strikes a nail with a hammer moving with a velocity of 20 ms. the hammer comes to rest in 0.02 s after striking the nail. calculate the acceleration of the nail.

Answer 1

Acceleration of nail can not be calculated, since there is not any data about the nail. However, the acceleration of hammer can be calculated as,

$a=\frac{v-u}{t}=\frac{0-20}{0.02}=-1000m/s^2$
