After a 70-kg person steps from a boat onto the shore, the boat moves away with a speed of 0.70 m/sm/s with respect to the shore. If the same person steps from the shore onto the boat, the person and the boat move away from the shore at a speed of 0.50 m/sm/s. Assume that the initial speed of the person with respect to the shore is the same in both cases and that the person is moving in a horizontal direction. A. Determine the mass of the boat. B. Determine the speed of the person.
