Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”

Figure P5.27 shows the horizontal forces acting on a sailboat moving north at constant velocity, seen from a point straight above its mast. At the particular speed of thee sailboat, the water exerts a 220-N drag force on its hull and ɵ= 40.0°. For each of the situation (a) and (b) described below, write two component equations representing Newton's second law. Then solve the equations for P(the force exerted by the wind on the sail) and for n(the force exerted by the water on the keel). (a) Choose the x direction as east and the y direction as north.
