A car is waiting for the green light at the intersection. When the green light is on, the car starts to drive at an acceleration of 3m / S2. Just then, a bicycle passes by the car at a speed of 6m / S2. How long does it take for the car to run from the intersection before chasing the bicycle? How to get the distance between the two cars?

The car starts from 0m / s to do the uniform acceleration straight-line movement to catch up with the bicycle. The bicycle does the uniform speed straight-line movement of 6m / s, so before the instantaneous speed of the car reaches 6m / s, the distance between them is always increasing. When the speed of the car reaches 6m / s, the distance between the two cars is the farthest
