##### Solution Summary

The solution gives all mathematical steps. Newton's law of motion for sliding down a slope is determined.

##### Solution Preview

The total mass of the child + sled = 25 Kg, we will consider this as a single mass. The only force acting on the mass when it is at the top of the slope is the force due to gravity which is equal to

F = mg

This acts vertically downwards.

But ...
