A water jet starts at a point X and reaches its maximum height at a point Y. Air resistance has a negligible effect on the motion of the water jet. (i) State the direction of the force acting on the jet at Y. (1 mark)
(i) The only force acting on the water jet is gravity which always acts vertically downwards so the force at Y, as well as every point between X and Y, is down.Simply writing "down" would still get (1 mark).
