The graph shows how the speed v of a car varies with time t. 10·0 15·0 12·0 0 0 v (m s-1) t (s) The average speed of the car during the 12·0 s is A 1·25 m s-1 B 2·08 m s-1 C 2·50 m s-1 D 7·50 m s-1 E 12·5 m s-1. 2. A stone is thrown at 50° to the horizontal with a speed of 15 m s-1. 15 m s-1 50° Which row in the table gives the horizontal component and the vertical component of the initial velocity of the stone? Horizontal component (m s-1) Vertical component (m s-1) A 15 sin 50 15 cos 50 B 15 cos 50 15 sin 50 C 15 cos 50 15 sin 40 D 15 cos 40 15 sin 50 E 15 sin 50 15 cos 40 [Turn over
