The diagram below shows the speed time graph for a train travelling between two stations
The diagram below shows the speed time graph for a train travelling between two stations. The train starts from rest and accelerates uniformly for 150 seconds. It then travels at a constant speed for 300 seconds and finally decelerates uniformly for 200 seconds. Fig.Given that the distance between the two stations is 10 450m, calculate the:(a) maximum speed, in km/h, the train attained;(b) acceleration;(c) distance the train traveled during the last 100 seconds(d) time the train takes to travel the...

1. A car accelerates from zero to 105 km/h in 5.21 s. What is its average acceleration in km/h/s and m/s? 2. An object moving in the x-direction has a position described by the function x(t) - 6.30t + 8.70t2, where t is in seconds and x is in meters. What is the acceleration as a function of time? The figure shows the graph of v vs t for the motion of a motorcyle that starts from rest and moves...
