a body at rest is given an initial uniform acceleration of 18m/s squre for 30sec...
a body at rest is given an initial uniform acceleration of 18m/s squre for 30sec after which the acceleration is reduced to 5m/s squre for the next 20sec. the body maintains the speed attained for 60sec after which it is brought to rest in 20sec.
a)draw the velocity time graph of the motion
bi)using the graph calculate the maximum speed attained during the motion.
ii)calculate the average retardation as the body is being brought to rest.
iii)calculate the total distance traveled during the first 50sec
iv)calculate the average speed during the same intervals as seen in question iii?
