Need help/hints on incline problem

  1. Sep 29, 2004 #1
    a block is projected up a frictionless inclined plane. the angle of incline is 35 degrees, and the initial velocity is 8.2 ft/s. how far up the plane does the block travel? how long does it take to get there? and what is its speed when it gets back to the bottom?

    Use conservation of mechanical energy.
