A student holds a 2.0 kg air rifle, un-braced with a very loose grip. The muzzle velocity of a 2.0 g bullet fired from the rifle is about 140 m/s. What is the recoil speed of the gun? What could the student do to reduce the recoil speed of the air rifle? Explain.​

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

newton's first law of motion
