Question

A car is travelling at a constant velocity of 20m/s while a truck is travelling in front of the car at 18m/s. The car decides to take over the truck and accelerates 2.0m/s^2 in 4.0 seconds. How far did the car travel in those 4.0 seconds?

Answer 1

$$s=v_0t+0.5at^2$$

$$s=(20)(4)+0.5(2)(4)^2=96\ m$$
