High speed stroboscopic photographs show that the head of a 198 g golf club is traveling at 56.6 m/s just before it strikes a 45.0 g golf ball at rest on a tee. After the collision, the club head travels (in the same direction) at 41.0 m/s. Find the speed of the golf ball just after impact.
Spheres A and B are touched together and then separated. Sphere C is then touched to sphere A and separated from it. Lastly, sphere C is touched to sphere B and separated from it. Explain how much charge ends up on sphere C?
