1. The problem statement, all variables and given/known data 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. 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. If the biker just barely catches up to the car as the car accelerates, how far from the intersection will the biker just catch up to the car? Put your answers only using variable d, not v and a. 2. Relevant equations xfinal = xinitial + vt xfinal = xinitial + vinitialt + 0.5at2 3. The attempt at a solution xbike = -d + vbiket xcar = 0 + 0 + 0.5at2 Because they should meet at the same location... xbike = xcar -d + vt = 0.5at2 d = vt - 0.5at2 But the solution still has v and a, so I am completely stuck.
