# Problem i have the answer to, but need the formula

• tommy1
In summary, the question asks where a truck, traveling at 17 m/s to the north, and a car, 450 m to the north and traveling south at 22 m/s, will meet. The car's speed decreases at a rate of 3.5 m/s^2. The answer is 381 meters. The necessary equations for solving this problem are the basic kinematic equations, specifically the equations for velocity and displacement. It is important to review and understand these equations for the final exam.

## Homework Statement

A truck is traveling at 17 m/s to the north. The driver of a car, 450 m to the north and traveling south at 22 m/s, puts on the brakes and slows at 3.5 m/s2. Where do they meet?

## Homework Equations

i know it is just the basic kinematic equations. but i don't really know which one or anything

## The Attempt at a Solution

i got the answer to be 381 meters. I did this months ago in the beginning of the year so i kind of forget how to do a lot of this. I am reviewing for my final so if you could show me the equations i would really appreciate it.

Surely the equations are listed in your book and/or notes. You really should try to figure out which one it is. Even if you guess wrong, it's still better than not trying at all. You won't pass the final anyway if you don't put forth the effort.

i have tried to figure this one out. It is the only one i am stuck on from this chapter. part of my notebook got ruined so i am working with limited resources. do not worry though i am putting effort into passing my exam. I am not lazy.

Great, then please show us one of your attempts.

v = u + at

s = ut + (1/2)at^2.

And look after them!
