The Attempt at a Solution
I submitted some homework in for marking & received back that on my last question (iii) I had worked out 37.5 wrong, could someone please have a look at my working & advise on where I am making the error.
I'm not sure if the tutor means 37.5 at 1 or 3.
I assume 3 as it says I have questions (i) & (ii) correct.
A vehicle of mass 1200 kg accelerates uniformly from rest to a velocity of
15 m/s in 5 seconds. It continues at this velocity for 15 seconds before decelerating uniformly at a rate of 5m/s2 to rest. Determine the following:
(ii)The time taken to decelerate from 15 m/s to rest
(iii)The total distance travelled
