A 40.0 kg child is standing on a 42 kg raft that is drifting with a velocity 0f 1.2 m/s [N] relative to the water. The child walks on the raft with a net velocity of 0.71 m/s [E] relative to the water. Fluid friction between the raft and the water is negligible. Determine the resulting velocity of the raft relative to the water. i and j vectors are not permitted. dont forget the angle
