You're driving down the highway late one night at 20m/s when a deer steps onto the road 35m in front of you. Your reaction time before stepping on the brakes is .5s, and the maximum deceleration of your car is 10m/s.

A. How much distance is between you and the deer when you come to a stop?

B. What is the maximum speed you could have and still not hit the deer?

So I don't think I started the problem correctly....

I used the equation d=v0*t+1/2a*t^2

so then d=20*.5-1/2*10*.5^2

d=8.75

so then I subtracted 8.75m from 35m and got 26.25m

It was wrong, then I thought 8.75 was it but that was wrong so I don't know what I did wrong. Could someone tell what I did wrong. I think it might of been the equation so I look for a problem like that in my book but couldn't find anything. Please someone help. Just the equation don't ruin the fun
