Three people are floating on a 120kg circular raft that is at rest in the middles of a pond. They decide to go swimming, and all jump off the raft at the same time and from evenly spaced distances around the perimeter of the raft. One person with a mass of 62kg jumps off at a speed of 12 m/s headed 0 degrees. The eecond petson of a mass of 73 kg jumps off the raft at a speed of 8 m/s headed at 120 degrees. The third person of a mass of 55kg jumps off at a speed of 11 m/s headed 240 degrees. What are the magnitude and direction of the veolcity of the raft immediately after the people jump off?
