Homework Statement



Two objects are at rest on a frictionless surface. Object 1 has a greater mass than object 2. When a constant force is applied to object 1, it accelerates throught a distance d. The force is removed from object 1 and is applied to object 2. At the moment when object 2 has accelerated through the same distance d, which statements are true? (Select all that apply.)
p1 > p2 True
K1 = K2 False
K1 < K2 True
p1 < p2 False
p1 = p2 False
K1 > K2 False


Homework Equations



Potential Energy - Stored energy; the energy an object has because of its position.
Kinetic Energy - The energy that a moving object has due to its motion, the energy of motion.

Could Someone please let me know if I am thinking about this problem wrong? And if I am, any help would be greatly appreciated.

Thanks

Why do you think that potential energy is relevant to this problem?

Work done = Force X displacement. When work is done on a body by a force for a distance d, and there is no dissipation of energy, then that work done must be equal to the KE of the body at the end of the distance d.
