A body accelerates uniformly from rest to a speed of 10m/s, then moves at constant speed for a time and finally decelerates
uniformly to rest. The distance moved during the uniform motion phase is half of the total distance covered. If the acceleration is
thrice the deceleration and the total time is 18 seconds, find the acceleration.
