Ok, this isn't a homework question, I've been out of school for quite some time but I'm having an argument with a buddy how to solve this - I know it's straight out of high school physics but it's been a loooooong time since high school physics... :)
You have a car going 44 ft/s - now you want to come to a complete stop in a distance of 132 ft and a time of 3 seconds. What is your required deceleration going to be to come to a stop?
I thought we just use d = .5 * a * t^2, working that we get a deceleration of 29.33 ft/s^2, but my buddy thinks I'm wrong - but they don't have a "right" solution either!
So am I wrong or right here, and if I am wrong, what is the correct solution to my problem?
