A raft is on the surface of a river. The river current applies a force of 120 N to the South, and the wind applies a force of 30 N to the East. Calculate the magnitude and direction of the net force on the boat.

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
