A 4.0 g bullet leaves the muzzle of a rifle with a speed of 310 m/s. What force (assumed constant) is exerted on the bullet while it is traveling down the 0.9 m long barrel of the rifle?

Force x distance = Work done on bullet
= kinetic energy increase = (1/2)MV^2

Solve for the Force

Hello. I keep repeating the problem and I get a huge number.

Show your work. Make sure the mass of the bullet is converted to kg.

F = (1/2) M V^2 / (0.9 m)

The answer will be in Newtons if m is in kg and V is in m/s.
