A 30-caliber rifle with a mass of 2.80 kg fires a 9.84- g bullet with a speed of 726 m/s with respect to the ground. What kinetic energy is released by the explosion of the gunpowder that fires the bullet?

1 answer

by conservation of momentum
2.8 * speed of rifle back = .00984*726
solve for speed of rifle back, Vr

Ke = (1/2)(2.8)(Vr)^2 + (1/2)(.00984)(726)^2
