3. A car speeds up from 10.0 m/s to 30.0 m/s in 3.0 s. What is its acceleration? In your response, show your work, the given and unknown quantities, the equation and any necessary algebra. Express your answer with the correct number of significant digits.

a = (Vf  Vo) / t,
a = (30  10) / 3 = 6.67m/s^2.
