Question

Two blocks, Block A and Block B, are initially at rest. A total force F is applied to Block A, of mass M, for a distance D. The same force F is applied to Block B, of mass 2M, for the same distance D. Which block has the larger kinetic energy at distance D? (a) Block B. (b) Both blocks end up with the same kinetic energy. (c) Block A.

Step 1

This work is converted into kinetic energy. So, the kinetic energy of each block at distance D is equal to the work done on it. The work done on Block A is F*D, and the work done on Block B is also F*D, because the same force is applied over the same distance. Show more…
