Question: An object moves along the x-axis so that its position at any time t 2 0 is given by x (t) = cos (2t2 -

An object moves along the x-axis so that its position at any time t 2 0 is given by x (t) = cos (2t2 - t + 5) . Find the velocity of the object as a function of t. O A. - sin (2t2 - t + 5) O B. (4t + 1) sin (2t2 - t + 5) O C. - (4t - 1) sin (2t2 - t + 5) D. cos (4t - 1) sin (2t2 - t + 5) O E. - sin (4t - 1)
