An 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?

    Shouldn't this be on the homework forum?

    Find the acceleration of the body along the incline and use kinematics.

    I think the acceleration would be -g*cos(35), from that use constant acceleration equations to solve the problem.

    It will be with sine. Of course with no friction.

    And due to conservation of energy and lack of friction (external force) without even solving the problem we can say it would come back down with the same speed...
