The Acceleration of an Object as a Function of Time

question 114

Multiple Choice

The acceleration of an object as a function of time is given by a(t) = (3.00 m/s³) t. 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?

• A)33.0 m
• B)30.0 m
• C)36.0 m
• D)27.0 m
• E)Not enough information is given to determine the displacement of the object between these two times.
