Car C and car D are both stopped at the similar intersection. At t=0 sec car C starts to accelerate from rest at a constant acceleration of 1.5 m/s2. At t=5 sec, car D starts from rest and accelerates in the similar direction at 3.0 m/s2.
Determine how far have the cars travelled when the meet? (You will need to use a quadratic equation and also draw displacement, velocity and acceleration by time graphs to help you solve)
