A body at rest is given an initial uniform acceleration of 8m/s2,for 30s.after which the acceleration of 8m/s2 is reduced to 5m/s2 for the next 20s. The body maintains the speed attain for 60s, after which it is brought to rest in 20s.Draw the velocity time gaphy of the motion using the graph to calculate
a) Maximum speed attained during the motion
b) Average retardation as the body is been brought to rest
c) Total distance traveled during the first 50s
d) Average speed during the same interval as in (c) above?
