An object moves along a line so that its position at any time t > 0 is given by the function x(t), with t measured in seconds. The derivative of a(t) at t = 1 calculates: Select one: )a. The displacement of the object during the first cross out second. O b. The average velocity of the object between 0 cross out and 2 seconds. O c. The instantaneous velocity of the object when cross out t = 1. O d. The position of the object when t = 1. cross out Clear my choice
