Homework Statement
A block of mass 13.0 kg slides from rest down a frictionless 35.0° incline and is stopped by a strong spring with k = 2.60 x 10^4 N/m. The block slides 3.00 m from the point of release to the point where it comes to rest against the spring. When the block comes to rest, how far has the spring been compressed?
Homework Equations
F=mg (weight of block in Newtons)
The Attempt at a Solution
I've found the weight of the block in Newtons (127.4 N), and I know that I have to find the force of the spring in its direction. To get the final answer, I'd have to divide that by the value of k. But I don't know how to find the force of the spring!
