A 2.0 g bullet leaves the barrel of a gun at a speed of 300m/s. (a) Find its kinetic energy. (b) Find the average force exerted on the bullet by expandin gases as the bullete moves the length of the 50 cm long barrel.
I did (a), but I am not sure if it is correct. I tried (b), but I don't know what to do next?
(a)W=(1/2)(.002kg)(9.8m/s^2)(300m/s)2=882J
(b)50cm->5m

Recall that:
Kinetic energy = (1/2)(m)(v^2)
Your formula for kinetic energy is not correct.
