Another Catch Problem I'm lost at!!! My physics teacher is spitting these catch problems at me like a maniac. Here's the question (it was on my test and I was partially clueless): A girl is trying to running as fast as she can at a constant velocity of 4.5 m/s . She is trying to catch her boyfriend's car which is at rest behind the red light. Just when the girl is 10m behind the car, the light changes and the car accelerates at 1 m/s^2. How far will the girl have to run in order to catch the car? Also 'she can not catch the car' was one of the choices in the multiple answers. In order for the girl to catch the car, they need to be at the same position in the same time. I sketched a d/t graph for this. The graph simply summarizes my thoughts on this problem. Can someone please walk me through the calculations needed to solve this problem. Also, if someone out there has some tips about these kinds of problems please tell them to me. I'm really struggling at these.
