A car travels 80 metres in the first 10 seconds and then 80 metres in the next 20 seconds. If the acceleration is constant, find:
a) How much further it will travel before coming to rest
b) How many more seconds it will travel before coming to rest
**This question uses some/all of the following 4 formulas:
v = u + at
v^2 = u^2 + .5at^2
s = ut + .5at^2
s = .5 (u + v)t
This is all the information I was given, the question doesn't specify whether the vehicle starts from rest or not.
Thanks
