A body at rest is given an initial acceleration of 8.0m/s² for 30s after which the acceleration is increased to 12.0m/s² for the next 20s. The body maintains the speed attained for 60s after which it is brought to rest in 20s. Draw the velocity time graph of the motion. Using the graph, determine;
A) Maximum speed attained during the motion
B) Average retardation as the body is brought to rest
C) Total distance travelled during the first 50s
D) Average speed during the same interval in C) above?
