4. Marlene, a 45.4kg girl is running at 3.5m/s on a pier from the shore towards a lake. At the edge of the pier she jumps onto a raft in the water. The raft was originally drifting towards the pier with a drift speed of v= -1m/s. What is the speed of Marlene and the raft if the mass of the raft is 112kg ?
