Question: A car is stopped at an intersection with a red light, and a biker (in a bike lane) with velocity "v" is approaching the car from behind. When the biker is a distance "d" from the intersection, the light turns green, and the car begins to accelerate at a constant acceleration "a".
Part A: In terms of only "d" (not "v" and "a") calculate the distance at which the biker catches the car if he only barely catches it while it is accelerating.
I want help to find calculate the distance at which the biker catches the car if he only barely catches it while it is accelerating.
