Problem
A 0.25 kg model rocket is coasting horizontally due east at 12 m/s when its engine fires for 0.040 s. During the burn the exhaust produces a constant 30 N force due north, while air resistance exerts 5.0 N due west. Find the rocket’s speed and the direction of its motion (angle measured north of east) immediately after the burn ends.
