1) An 82 kg man is at one end of a homogeneous platform of 26 kg and 4.6 m long initially at rest. It can walk at 2.4 m/s relative to the platform, which can roll freely. (a) Where is the CM of the system initially in relation to the human? ( b) What is the modulus of the velocity of the platform as the man walks to the other end? (c) How far did the platform move when the man reached the other end?
