A 80 kg man is ice-skating due north with a velocity of 6.0 m/s when he collides with a 35 kg child. The man and child stay together and have a velocity of 3.0 m/s at an angle of 35° north of due east immediately after the collision.
(a) What is the magnitude of the child's velocity just before the collision?
m/s
(b) What is the direction of the child's velocity just before the collision?
° (south of east)
