The position of an object is given as a function of time as x(t) = (3.00 m/s)t + (2.00 m/s²)t². What is the average velocity of the object between t = 0.00 s and t = 2.00 s? A)3.00 m/s B)11.0 m/s C)27.0 m/s D)13.0 m/s E)7.00 m/s

The average velocity is the total displacement divided by the total time. At t = 0, x(0) = 0. At t = 2, x(2) = (3.00 m/s)(2) + (2.00 m/s²)(2)² = 6 + 8 = 14 m. Average velocity = (14 m - 0 m) / (2 s - 0 s) = 7.00 m/s.
