A block is shot up a frictionless 40degree slope with intial speed v. It reaches height h before sliding back down. The same block is shot with the same speed up a frictionless 20 degree slope. On this new slope, the block reaches height?

2. Relevant equations

1/2 mv^2 I'm not sure how to transfer this equation for speed and height when dealing with angles

3. The attempt at a solution
