B) Mass and friction
C) Velocity and mass
D) Friction and velocity

Question

Quizplus · Accepted Answer

The kinetic energy of a bullet is directly proportional to its mass and its velocity. The higher the mass and velocity, the higher the kinetic energy. Friction does not directly affect the kinetic energy of the bullet, but it does contribute to the loss of energy over distance traveled.
