Question

ANSWER NUMBER 2- (i) Sketch the velocity–time graph for the train’s journey.

2. A train travels from A to B, a distance of 20 000m, taking 1000s. The journey has three stages. In the first stage the train starts from rest at A and accelerates uniformly until its speed is Vms. In the second stage the train travels at constant speed Vms¯1 for 600 s. During the third stage of the journey the train decelerates uniformly, coming to rest at B. (i) Sketch the velocity-time graph for the train's journey. (ii) Find the value of V. Given that the acceleration of the train during the first stage of the journey is 0.15ms? , find the distance travelled by the train during the third stage of the journey (iii)
