The professor gave this problem in class today and i have tried all the formulas and apparently I am not doing something right. I am pretty sure the answer is about 1.5 seconds. This is the problem: A crook is driving at a constant speed 85 mph. He zooms past a cop. It takes the cop 4 seconds to react. He goes from 0-95 in 14 seconds. How long does it take the cop to catch the crook.
