You're driving down the highway late one night at 15 m/s when a deer steps onto the road 42 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 11 m/s^2 .

1.

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

Express your answer using two significant figures.

2.

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

Express your answer using two significant figures.

Solutions

Expert Solution

0 = u2 + 2* (-11) * 34.5 u2 = 759 u = 27.5499 m/s u = 28 m/s ( two significant figure)

hence , maximum speed you could have and still not hit the deer is 28 m/s

if you have any query please comment

Question: You're driving down a country road at 25 m/s, when a deer suddenly starts crossing the road. As soon as you react, you hit the brakes to decelerate the car at a rate of 4.20 m/s2. If the deer is 77 m ahead of you, do you hit the deer with your car?
