Homework Help: Frictionless ramp

  1. Nov 15, 2011 #1
    1. A 10 kg mass initially at rest is pushed along a level frictionless track by an applied force angled at 45 degrees. The force is exerted for 50m before the mass reaches a ramp and is launched upward to a maximum of 57 meters. how much work did the force do on the mass and what is the magnitude of the applied force.

    2. Fnet=ma
    w=ke+pe

    3. I am not sure where to start
