Question

A 100-kg crate is subjected to two forces: a 500 N force directed at 45° above the horizontal (pulling upward-left) and a 400 N force directed at 30° below the horizontal (pushing inward from the right). The crate is originally at rest on a horizontal surface. Determine the distance $s$ it must slide in order to attain a speed of $v = 8\text{ m/s}$. The coefficient of kinetic friction between the crate and the surface is $\mu_k = 0.2$. Use the work-energy principle.
