1. The 80 kg man dives from the 40-kg canoe. The velocity indicated in the figure is that of the man relative to the canoe just after the loss of contact. If the man, woman, and canoe are initially at rest, determine the horizontal component of the absolute velocity of the canoe just after separation. Neglect drag on the canoe, and assume that the 60.kg woman remains motionless relative to the canoe. 3 m/s 90 kg 60 kg 40 kg 30°
