## Homework Statement

A spring at top of a 30 degree slope is compressed 0.5m by a 0.5 kg book. If the book is released, it will just reach the edge of the slope at the spring's equilibrium point, and then it will start to slide down the slope. Assume the spring constant is 25 kg/s^2. Assume X-direction and Y-direction mean left-right, up-down as usual.

a) If the slope is frictionless, what will be the speed of the book after it has traveled a distance 5 meters in the x direction?

b) IF the book's mass is doubled, does your answer for (a) change, and if so, by how much (b)?

## Homework Equations

Fsp = -k(s)

## The Attempt at a Solution

I have made a diagram of what the problem is trying to make me visualize. I understand physically what is going on but however I don't how to start off with a right equation. There is just too many unknowns that is given. Part B is straightforward, it's just Part A I'm running myself into a wall.
