Homework Statement
Suppose that a woman driving a Mercedes zooms out of a darkened tunnel at 30.3 m/s. She is momentarily blinded by the sunshine. When she recovers, she sees that she is fast overtaking a camper ahead in her lane moving at the slower speed of 13.7 m/s. She hits the brakes as fast as she can (her reaction time is 0.34 s). If she can decelerate at 2.9 m/s2, what is the minimum distance between the driver and the camper when she first sees it so that they do not collide? (Note that she decelerates to 13.7 m/s)
Homework Equations
The Attempt at a Solution
30.3*0.34 = 10.3 m
And I can't do the rest. I've tried 5 different approaches with different answers and still got it wrong. I don't exactly understand how to do the question. All help is appreciated.
