Correct Answer:
A
Basic kinematics variables using calculus: The acceleration of an object as a function of time is given by a(t) = (3.00 m/s3)t, where t is in seconds. If the object has a velocity 1.00 m/s at time t = 1.00 s what is the displacement of the object between time t = 2.00 s and time t = 4.00 s?
