1. The problem statement, all variables and given/known data a ball with mass m and velocity v is moving up a wedge of mass M. What height does the ball reach if: a) the ramp is fixed on the table b) the ramp is able to move on a frictionless surface 2. Relevant equations mgh (1/2)mv(squared) 3. The attempt at a solution for a) i just solved for h using both equations given above, since there is a loss in kinetic energy which is converted to a gain in gravitational potential energy as the ball moves up the wedge. so this gives me that the h = v(squared)/2g. im stuck on b) however.
