Question
A car with a mass of 1264 kg is coasting in neutral on a straight,level road. It slows down, and its speed as a function of time is given by the equation:
Constant Value Units
a 26.8 m/s
b 0.310 m/s2
c 2.10·10-3 m/s2
At a time of 36.0 s the speed, as given by the above equation, is 18.36 m/s. Calculate the power which the engine must deliver (to compensate for air resistance and rolling resistance) in order to maintain that speed.

Answers
the equation:
v(t) = a − bt + ct2
v(t) = a − bt + ct2
