A large heavy sphere and a small light sphere are dropped Comprehension I together onto a flat surface from a height h The radius of spheres is much smaller than height h The large sphere collides with the surface with velocity vo and immediately thereafter with the small sphere The spheres are dropped so that all motion is vertical before the second collision and the small sphere hits the larger sphere at an angle a from its uppermost point as shown in the diagram All collisions are perfectly elastic and there is no surface friction between the spheres h A C 30 2 a B 2a D zero a Prob 1 The angle made by velocity vector of small sphere with the vertical just after the second collision in the frame of large sphere l
