A sphere with a mass of .3 kg and a radius of 15 cm starts from rest on a 22 degree incline 50 cm above a horizontal surface. It rolls without slipping down the incline. After it rolls on the horizontal surface for a short distance it collides iwth a .5 kg block, wherer it sticks (and stops rolling). What is the velocity of the combined sphere/clock system after the collision?
