Part A = v = sqrt(2gh(μkcot(α) + 1))
Express your answer in terms of some or all of the variables m, g, h, μk, and α.
There are several ways to approach this problem. The easiest is just to figure out the forces from gravity and kinetic friction, and make sure the velocity is high enough to overcome them. When you solve, you actually remove mass from the equation. The answer that mastering physics is looking for is:
v = sqrt(2gh(μkcot(α) + 1))
