Homework Statement
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
Homework 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
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 textbooks I can buy/download as my school assigned us Glencoe's Physics : Principles and Problems.
