Q1. The wind blows with a force of 425N north on a sail boat, while the water exerts a force of 325N west on the sailboat. Find out the magnitude and direction of the net external force on the sailboat.
Q2. Soccer player 1 is 8.0 m from the goal, as the drawing shows. If she kicks the ball directly into the net, the ball has a displacement labelled. If, on the other hand, she first kicks it to player 2, who afterwards kicks it into the net, the ball undergoes two successive displacements, y and x. What are the magnitude and direction of x and y?
