Multiple Choice
A box of mass m and a box of mass 4m are sliding with equal speeds along a level frictionless surface. Then they both slide up the same frictionless hill. Which rises to a greater height?
A) The box of mass m because it is lighter and its inertia is smaller.
B) The box of mass m because it has less kinetic energy and therefore more potential energy.
C) Both boxes slide to the same height.
D) The box of mass 4m because it is heavier.
E) The box of mass 4m because it has a larger kinetic energy and therefore more potential energy.
