Question
is my answer right, if not fix it plz
![43. A 40.0 kg child is standing on a 42 kg raft that is drifting with a velocity Of 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
