Homework Statement
You are trailing a car by 25m; both you and the car are traveling at 110km/h. Your attention is diverted for 2.0s. At the beginning of that 2.0s, the car in front of you brakes at 5.0 m/s^2.
Suppose your attention is diverted another .40s. If you too break at 5.0m/s^2, what is your speed when you hit the car?
Homework Equations
v^2 = u^2 + 2at ?
x = x0+(v0*t) + 1/2at^2 ?
The Attempt at a Solution
I converted everything to m/s. However, I do not understand which equation I can use that incorporates velocity, time, and position. I'm assuming that I'm suppose to create functions for both cars and set them equal to each other.
Any help will be greatly appreciated.
