## Homework Statement

You're driving down the highway late one night at 16 m/s when a deer steps onto the road 39 m in front of you. Your reaction time before stepping on the brakes is 0.50 s, and the maximum deceleration of your car is 12 m/s^2 . How much distance is between you and the deer when you come to a stop? What is the maximum speed you could have and still not hit the deer?

## Homework Equations

reaction time is 1/2 of 16m so it is 8m

x=vot*.5at

## The Attempt at a Solution

t=1.33 s

I know there are 20 meters between me and the deer because I was able to figure out the first part of the question with help from my brother. I can't remember the calculations because I left my physics book in my room and I'm in the library currently.

I know we tried two different ways to solve the problem and got wrong answers. Honestly, I don't even know how to start the second half of the problem. Please give me an outline on what to do, at least, so I can figure this problem out. Thank you!
