Question 6: A body at rest is given an initial uniform acceleration of 6.0ms for 25s after which the acceleration is reduced to 4.0ms for the next 15s. The body maintains the speed attained for 40s after which it is bought to rest in 20s. (a) Draw the velocity time graph of the motion. (b) Using the graph, calculate the (i) (ii) (iii) (iv) maximum speed attained during the motion average retardation as the body is being brought to rest total distance travelled during the first 80s average speed during the same interval as in (iii)
