DESPERATE NEED OF HELP ON THIS Physics PROBLEM!
Okay for those who are really smart in Physics, please help! I've been staring at this problem for hours and I just can't figure it out. I know that you need to find the final velocity and then time, but it just seems like there's not enough information. Well here's the problem:
An unmarked police car, traveling a constant 90 km/h, is passed by a speeder traveling 140 km/h. Precisely 1.00s after the speeder passes, the policeman steps on the accelerator. If the police car's acceleration is 2.00 m/s2, how much time elapses after the police car is passed until it over takes the speeder (assumed moving at constant speed)?
I don't need the answer or anything, I just need to know where to start off 'cause I'm totally stuck. If you figure it out please email, message, or even IM me on MSN at pesstimisticgurl23@yahoo.com.Thank you so much!
