Newtons Laws

  1. Oct 23, 2006 #1
    I need help with this problem:
    A block is given an initial speed of 3.0 m/s up a 22.0 degrees plane. (A) How far up the plane wll it go? (B) How much time elapses before it returns to its starting point?

    I know the acceleration is -3.67 m/s^2, but I have no idea how to continue on. I don't know what equation to use to figure out (A). Please help!

    You just have to realize you have a regular kinematics question in 1D now. You know the initial speed and you know the acceleration. That should be enough to find the distance and time.
