Short computation The position of an object as a function of time is given by x(t) = bt2 - ct, where b = 2.2 m/s² and c = 7.1 m/s. What is the instantaneous velocity v of the object when t = 7.9 s? v = ______ m/s Remember to include a "-" if the velocity turns out to be negative. Do not include a "+" for a positive value. Report your numerical answer below, assuming three significant figures.
