(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A car initially traveling at 15 m/s accelerates at a constant rate of 4.5 m/s^2 over a distance of 45 m. How long does it take the car to cover this distance?

Vi: 15 m/s

Vf: ___ m/s

A: 4.5 m/s^2

Delta D: 45 M

Delta T: ___ s

2. Relevant equations

I'm guessing I would have to use this Kinematics equation:

Delta D (Displacement) = Vi * Delta T (Time) + 1/2 * A * Delta T^2

3. The attempt at a solution

I tried attempting this problem but had trouble rearranging the equation to solve for the missing variable T.

Could someone give me a basic rundown on HOW TO rearrange equations as I never really learned and or understood this concept.

Lastly, what are some good classical/intro physics text books I can buy/download as my school assigned us Glencoe's Physics : Principles and Problems.
