Problem
Two objects are initially at rest on a frictionless surface. Object 1 has a greater mass than object 2. The same constant force starts to act on each object. The force is removed from each object after it accelerates over a distance d. After the force is removed from both objects, which statement is correct (p: momentum; K: kinetic energy)?
(a) p₁ < p₂; (b) p₁ > p₂; (c) K₁ > K₂; (d) K₁ < K₂.
