A 40 kg child and her 75 kg father simultaneously dive from a 100 kg boat that is initially motionless. The child dives horizontally toward the east with a speed of 2m/s, and the father dives toward the south with a speed of 1.5m/s at an angle of 37degrees above the horizontal. Determine the magnitude and direction of the velocity of the boat along th mater's surface immediately after their dives.
I have no idea about the question, please help! thanks
