- A Train Starts From Rest At Cambridge Station And Accelerates Uniformly Until It Reaches A Maximum Speed Of 25 Ms It Th 1 (26.22 KiB) Viewed 29 times
A train starts from rest at Cambridge station and accelerates uniformly until it reaches a maximum speed of 25 ms. It then travels at this speed for a short time before decelerating uniformly, coming to rest at Great Shelford station. The train travels at its maximum speed for two thirds of the total journey time and takes 5 minutes to make the journey. (a) Sketch the speed-time graph, showing the information given. (b) Find the distance the train travels between Cambridge and Great Shelford stations. The magnitude of the acceleration is twice the magnitude of the deceleration. (c) Find the magnitude of the acceleration.
