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​

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

explanation:

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
