1. A .5 Kg block rests on a horizontal fricionless surface. The block is pressed back against a spring having a constant of K =625 newtons per meter. The spring is compressed .1 meters. Then the block is released. Find the maximum distance the block travels up the frictionless incline if the angle on the incline is 30 degrees. 2. 3. I set up the PE, KE, and spring .5kxsquared added up equal total energy. For hight, i used 0, where the only stored energy would be the spring(.5kxsquared), PE and Ke here is 0. Than I put H as it's max height(where it would stop on the incline). I don't know what H is though, and can't solve for V.
