**[SOLVED] Block released from spring slides up a ramp**

**1. Homework Statement**

**2. Homework Equations**

I'm thinking conservation of energy:

K

_{1}+U

_{1}+W

_{Other}=K

_{2}+U

_{2}

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/s

^{2}. 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!
