1. The problem statement, all variables and given/known data To save fuel, some truck drivers try to maintain a constant speed when possible. A truck traveling at 92.0 km/hr approaches a car stopped at the red light. When the truck is 121.2 meters from the car the light turns green and the car immediately begins to accelerate at 2.80 m/s2 to a final speed of 125.0 km/hr. How close does the truck come to the car assuming the truck does not slow down? and How far from the stop light has the car travelled when the truck reaches its closest distance? So what do I need to do here, im not even sure which equations to use. Do I need to set the x of both equal to each other? Can some one please walk me through this problem.
