The slope has a height of 4.0 m and makes an angle of 30 to the horizontal ground. Fig. 1.1 (a) In one instance, 17.0 m su  . (i) Calculate the maximum distance 0s from the bottom of the slope that the ball reaches. 0s = m [2] (ii) As the ball moves up the slope from the bottom, draw on Fig. 1.2 the variation with distance s travelled by the ball from the bottom of the slope of its 1. kinetic energy (label as EK), 2. potential energy (label as EP). Potential energy at the bottom of the slope is zero. [2] Fig. 1.2 s / m energy 0 0 30 4.0 m u ground ball
