The path of the ball is shown in Fig. 1.1. Fig. 1.1 The points S and F are on the same horizontal level. Air resistance is negligible. The ball is thrown from point S with velocity v, represented by the vector arrow shown in Fig. 1.1. On Fig. 1.1, (i) draw arrows from point S to represent the initial horizontal and vertical components of the velocity v (label these components vH and vV respectively). [1] (ii) draw arrows at A and at B to represent the horizontal and vertical components of the velocity of the ball at these two points. [3] (b) The horizontal distance from S towards F is x. (i) On Fig. 1.2, sketch the variation with x of the potential energy Ep of the ball. [1] Fig. 1.2 Ep 0 S F x
