Person A with a mass of 70kg has an initial velocity of 5 m/s. Is it possible for a second person to collide elastically with person A and have both their final velocities be 0? If so, what does the mass/initial velocity of the second person have to be? If not, why not? A large wheel is rolling along at a linear velocity of 5 m/s. The moment of inertia for the wheel is (3/5)MR2. It rolls up an inclined...
