Dynamics

A ball is launched up an inclined wall by a spring. The spring has a spring constant of 12.2 kN/m and is initially compressed 0.3m. The ball has a mass of 1.7 kg, a radius of 0.045m, and a moment of inertia of 0.0014kg*m^2. You can assume the ball rolls along the surface without sliding. The wall is inclined at an angle of 35 degrees to the horizontal. What is the velocity of the ball after it has traveled for 2.5m along the inclined wall?
