A- PRICE
B-QUANTITY
C-SUPPLY
D-DEMAND
E-EQUILIBRIUM POINT
Explanation:
It is the Supply Demand curve in Economics. It gives relationship between price and quantity
First put the speed in m/s. 120km/h = 33.33m/s. Now the position function is the integral of velocity, and velocity is in turn the integral of acceleration. The velocity is:

Now we integrate this expression to get the position. The constant of integration will be the distance the truck travels.

Here we set the distance, 35m as negative because I assumed the stopping point of the truck is the origin. Putting t=0 shows it starts at -35m.
Now solve the following equation for the time, t using the quadratic equation:

and choose the value t=1.149s
