A body at rest is given an initial acceleration of 6m/s² for 20 seconds, after which the acceleration is reduced to 4m/s² for the next 10seconds. The body maintains the speed attained for 30seconds. Draw the velocity time graph for the motion using the information given above. From the graph calculate; 1. Maximum speed attained during the motion
2. Total speed attained during the first 30seconds
3. Average speed during the time interval as in no. 2
