Basic Kinematics Variables Using Calculus: the Velocity of an Object

question 43

Multiple Choice

Basic kinematics variables using calculus: The velocity of an object is given by the expression v(t) = 3.00 m/s + ( 4.00 m/s³) t², where t is in seconds. Determine the position of the object as a function of time if it is located at x = 1.00 m at time t = 0.000 s.

• A) ( 4.00 m/s)t + 1.00 m
• B) (3.00 m/s)t + ( 1.33 m/s3)t³
• C) ( 4.00 m/s)t
• D) 1.33 m
• E) 1.00 m + (3.00 m/s)t + ( 1.33 m/s³)t³
