1. The problem statement, all variables and given/known data A block of inertia m is launched up a rough incline by a spring, as shown in the ﬁgure. The coeﬃecient of kinetic friction is µk. The angle of incline is θ, and the spring is parallel to the surface of the incline. The spring constant is k, and the spring has been compressed a distance d from its relaxed position. How far up the incline, from the point of release, does the block travel before it stops? 2. Relevant equations Im thinking of using the potential energy equation 3. The attempt at a solution Since its asking how far up, i would assume that we need to separate h in the potential energy equation, but this question really threw me off. How am I supposed to start with no numbers really?
