At an angle of α=30°with the vertical, a 5kg sphere is suspended on a string of length .8m with a initial velocity of 1.2m/s, it colides with wedge B. ε=.7 between the .9kg wedge and sphere A. A spring is attached to wedge B at the opposite end from where the sphere collides with B and has k=500N/m, angle of wedge is θ=20° with the vertical. Find the velocity of sphere A and wedge B immediately after impact.
