Vb = 8.0 m/s v1 = 0.2 m/s Your friend (mf = 53 kg) is skating slowly at 0.2 m/s directly towards you when you throw a wet football (mb = 1.0) kg at Vb = 8.0 m/s to them (see picture). What is the velocity of the center of mass of the friend + ball system? Give your answer in m/s to three decimal places
