**1.There are two parts to this question, and I can get the first part but do not know where to start for the second.**

It goes like this; You are driving down the highway late one night at 20m/s when a deer steps out on the road 35m in front of you. Your reaction time before stepping on the brakes is 0.50s, and the maximum deceleration of your car is 10m/s

^{2}.

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?

I did part a by finding the distance of 20m/s(0.50s) = 10m then adding it to the distance calculated from V2

^{2}-V1

^{2}/ 2(a) = 20m

so it came out to be 30m and 5m away from the deer.

**How do I calculate the max speed?**

Thanks for any help
