Question

(b) A body at rest is given an initial uniform acceleration of 6.0ms-2 for 20s after which the acceleration is reduced to 4.0ms-2 for the next 10s. The body maintains the
speed attained for 30s. Draw the velocity-time graph of the motion using the information
given above. From the graph, calculate the [3mks] (i) maximum velocity attained during the motion [3mks]
(ii) total distance travelled during the journey [3mks]
(iii) average speed of the motion. [3mks]
