Carmen and Judi dock a canoe. 83.0-kg Carmen moves forward at 4.3 m/s as she leaves the canoe to step onto the dock. At what speed and in what direction do the canoe and Judi move if their combined mass is 115 kg? (Use a positive number if the canoe moves away from Judi.)
Those are large girls. I am not so certain it is wise for Carmen to be walking in the canoe.
I don't understand the comment in the last ( ). Judi is in the canoe, the canoe cannot move away frm her.
