Ou are sitting in your car at rest at a traffic light with a bicyclist at rest next to you in the adjoining bicycle lane. as soon as the traffic light turns green, your car speeds up from rest to 49.0 mi/h with constant acceleration 7.00 mi/h/s and thereafter moves with a constant speed of 49.0 mi/h. at the same time, the cyclist speeds up from rest to 23.0 mi/h with constant acceleration 15.00 mi/h/s and thereafter moves with a constant speed of 23.0 mi/h.[hint: this is a great problem to use some graphs to you visualize what is going on. there are more than 2 important clock readings in this problem.] (a) for what time interval (in s) after the light turned green is the bicycle ahead of your car?
