Need help/hints on incline problem

[scottgregorysg]

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?
