Homework Statement
A .500 kg block rests on a horizontal, frictionless surface as in the figure below. The block is pressed back against a spring having a constant of k=625 N/m, compressing the spring by 10cm to point A. Then the block is released.
a) Find the maximum distance d the block travels up the frictionless incline if θ= 30°
b) How fast is the block going when halfway to its maximum height?
Homework Equations
Kinitial+PEinitial= Kfinal+PEfinal
not exactly sure what other equations to use
The Attempt at a Solution
First I found the velocity of the block using KE=PEs (1/2mv^2=1/2kx^2) and ended up with equation of v=√kx/m and got 11.18 m/s for velocity but not sure what to do next or if I'm even doing this right I have the answers as shown in my attachment but I'm struggling to figure out how to get there please help I just started this topic in my AP Physics B course :(
