A mother tows her daughter on a sled on level ice. The friction between the sled and the ice is
negligible, and the tow rope makes an angle of e to the horizontal. The combined mass of the sled and
the child is M. The sled has an acceleration in the horizontal direction of magnitude a . As we will learn
to justify in a few weeks, the child and sled can be treated in this problem as if they comprised a single
particle.
