A bullet of mass 20g enters into a fixed wooden block with a speed of 40 m s –1 and stops in it. Find the change in internal energy during the process.

Question

Philoid · Accepted Answer

Given:

Mass of bullet=20g

Initial speed = 40m/s

Formula used:

Kinetic energy =1/2 mv²

Change in kinetic energy=change in internal energy

16J =change in internal internal energy

A bullet of mass 20g enters into a fixed wooden block with a speed of 40 m s–1 and stops in it. Find the change in internal energy during the process.
