a body initially moving at 25ms-1 in 24 seconds accelerates uniformly at a velocity of 80ms-1 in 10 seconds. it then maintains a constant velocity for 50 seconds before going to in 16 seconds. sketch a velocity time graph for the body and use it to determine the total distance travelled and the acceleration in each section of its journey.
