To save fuel, some truck drivers try to maintain a constant speedwhen possible. A truck traveling at 28.0 km/hr approaches a carstopped at the red light. When the truck is 165.5 meters from thecar the light turns green and the car immediately begins toaccelerate at 2.4 m/s2. How close does the truck come to the carassuming the truck does not slow down?
How far from the stop light has the car travelled when the truckreaches its closest distance?
( ps. i can not solve it the way i thought about because i do nothave the final speed of the car ! )
