I'm struggling a bit with this question, it seems quite simple but I can't seem to get the right answer.. pls help: A car accelerates from rest at a rate of 3.5 metres per second squared for 6 seconds; it then travels at a constant speed for a further 8 seconds. Calculate the distance that the car has travelled in this time.

Okay so I take it you've done the equations of linear motion as this is in the A Level section, so a=3.5 ms^-2
For the first 6 seconds the distance is given by S=(at^2)/2
Then for the final 8 seconds the distance is given by S=ut. T=8 in this
