Homework Help: Rolling down an incline

  1. Feb 14, 2010 #1
    1. The problem statement, all variables and given/known data
    A solid cylinder of mass 10 kg is at rest atop a 10m high ramp inclined at an angle of 37 degrees. The cylinder is released and rolls, without slipping, down the incline. Then, the cylinder rolls across a rough 1-m long table that is 2m above the ground. Finally, the cylinder rolls off of the table. Calculate how far from the base of the table the cylinder lands.

    The friction is to be ignored because it allows the cylinder to roll, and doesn't hinder the motion.

    2. Relevant equations

    3. The attempt at a solution
    I've tried using kinematics, newtons 2nd and conservation of energy, but
    I can't figure out how far the cylinder lands plays into it.

    Hi amegirl24! Welcome to PF! :wink:

    The cylinder leaves the table with a horizontal velocity. Use ordinary projectile equations to find where it lands. :smile:
