A body at rest is given an initial uniform acceleration of 8.0m/s2 for 30 second after which the acceleration is reduced to 5m/s2 for the next 20 seconds.The body maintains the speed attained for 60 second after which it is brought to rest in 20 seconds.Draw the velocity time graph of the motion using the information given above.(c) using the graph, calculate the (i)maximum speed attained during the motion(ii) average retardation as the body is being brought to rest (iii)total distance travelled during. the first 50 secs (IV) average speed during the same interval as in (ii)?
