Asked by Ann

A 30-caliber rifle with a mass of 3.54 kg fires a 7.33- g bullet with a speed of 596 m/s with respect to the ground. What kinetic energy is released by the explosion of the gunpowder that fires the bullet? (Note there is a tolerance 0.1 percent for the answer)
Answered by Henry
KE = M*V^2/2 = 3.54*596^2/2 = 628,732 J
