6 A stone is thrown vertically upwards from the edge of a platform which is 10 m above the ground. The position-time graph for the motion of the stone is shown. The motion of the stone is in a straight line and the reference point for position is taken as a point at ground level, directly below where the stone was thrown. a From the graph estimate the instantaneous velocity with which the stone is thrown. position x (m) b What is the maximum height reached by the stone? c At what time does the stone reach its maximum height? d At what time does the stone hit the ground? 15- 10 5- 0 0.5 1.0 1.5 2.0 2.5 30 3.5 t (s)
