    Physics question

    How should I approach this problem? I don't know how I would even start to solve this.


    A 3-kg object is released from rest at a height of 5m on acurved frictionless ramp. At the foot of the ramp is a spring offorce constant k = 100 N/m. The object slides down the ramp andinto the spring, compressing it a distance x before coming torest.
    a) Find x.
    b) Does the object continue to move after it comes to rest? Ifyes, how high will it go up the slope before it comes torest?

    conservation of energy ...

    initial gravitational potential energy = elastic potential energy when the spring is fully compressed

    since there is no friction, is any energy "lost" in the transfer back and forth?
