[SOLVED] Block released from spring slides up a ramp 1. The problem statement, all variables and given/known data 2. Relevant equations I'm thinking conservation of energy: K1+U1+WOther=K2+U2 But really I'm not quite sure where to start here. 3. The attempt at a solution So far, I've calculated the velocity of the block after it leaves the spring, before it hits the ramp and I get that to be 3.553 m/s2. What is tripping me up here is the coefficient of friction, and how to apply that to the block as it travels up the ramp. If I turn the coordinate system so that the x axis is parallel to the ramp, then we can figure the x component of the velocity to be 3.553*Cos(38) I believe, but I'm not sure if that is useful to me or not. I think if I could get some confirmation on which direction to take with this that would be very helpful. Thanks!
