Question

Sarah is on a sled on the side of a hill inclined at 60°. The weight of the sled is 125 pounds. What is the magnitude of the force required for Sam to keep Sarah from sliding down the hill?

Answer 1

We will have that the force required will be:

$\begin{gathered} F=(62.5kg\ast9.8m/s^2)sin(60)\Rightarrow F=530.4405598...N \\ \\ \Rightarrow F\approx530.4N \end{gathered}$

So, the force required is approximately 530.4 N.
