Two titanium spheres approach each other head-on with the same speed and collide elastically. After the collision, one of the spheres, whose mass is 200 g, remains at rest.
(a) What is the mass of the other sphere?
(b) What is the speed of the two-sphere center of mass if the initial speed of each sphere is 3.0 m/s?
