2 A train is at rest in a railway station. At time t = 0, the train starts to move forwards with an increasing speed until it reaches its maximum speed at time t = 48 s. Fig 1.1 is the speed-time graph for the first 48s of the journey (a) (0 State how the graph shows that, during the first 48s of the journey, the acceleration of the train is constant [1]
(1) Calculate the acceleration of the train during the first 48s of the journey
