CSEC Physics · 1991 · Paper 2 · Question 3(d)(i)

A ball is thrown vertically upwards. A diagram shows positions at equal time intervals, with position A as the ball moves upwards and B at its highest point. Air resistance is ignored.

Draw on the diagram the force or forces acting on the ball at point A and at point B.
