Here’s a problem that I once gave on an in-class assessment:

A 2.6-kg block slides down a frictionless incline from point A to point B. A force (magnitude *P* = 3.4 N) acts on the block between A and B, as shown in the above figure. Points A and B are 2.2 m apart. If the kinetic energy of the block at A is 10 J, what is the kinetic energy of the block at B?
