AP Physics C: Mechanics
3.1 Translational Kinetic Energy
A cart of mass \(m\) moves along a straight, frictionless horizontal track. A net external force acts on the cart along its line of motion such that the magnitude of the cart's linear momentum increases by a factor of \(3\). What is the ratio of the cart's initial kinetic energy to its final kinetic energy, \(\dfrac{K_i}{K_f}\)?
