How do I solve this?

Question

Traveling at 60. mi/hr you see a dog in the road. Your reaction time to hit the brakes is 0.75 seconds and you can decelerate at 7.9 m/s^2. (1 mile = 1609 meters)

A) How far do you travel from the moment you see the dog until the moment you hit the brakes?

B) Over what distance does the car come to a stop once you hit the brakes?

C) What is the total stopping distance from the moment you see the dog?

Answer 1

a. distance=speed*time change mi/hr to m/s

b. vf^2=Vi^2+2ad a=-7.9m/s^2 solve for distance d.

c. total ? add distances in a and b.
