A car is travelling on a straight horizontal road, the velocity of the car v ms^-1 at time t seconds as it passes three point, P Q and R. It is modelled by the equation v=at^2+bt+c
The car passes P at time t=0 with velocity 8ms-1
c=8
The car passes Q at t=5 and at that instant its deceleration is 0.12 ms-2
The car passes R at t=18 with velocity 2.96 ms-1
b) determine the value of a and b
c) find to the nearest metre the distance between points P and R
