A vehicle of mass 1000 kg performs three stages of motion which are as follows:
1. accelerates uniformly from rest to a velocity of 20 m/s in 5 seconds.
2. continues at this velocity for 12 second.
3.decelerates uniformly at a rate of 5m/s2 to rest
Determine the following:
The acceleration in stage 1.
The time taken to decelerate from 20 m/s to
The total distance travelled over
the three stages
