Find the derivative of the function at the given point and interpret the physical meaning of this quantity. Include units in your answer.Suppose that the speed of a train approaching a station is given by v (t) = (t - 8) 2, for 0 ? t ? 8, where t is measured in seconds and v(t) is measured in meters per second. Find v'(5).
A. v'(5) = 6 m/s per second; the instantaneous rate of change in the train's speed is 6 m/s2 at t = 5 s. B. v'(5) = -3 m/s per second; the instantaneous rate of change in the train's speed is -3 m/s2 at t = 5 s. C. v'(5) = -6 m/s per second; the instantaneous rate of change in the train's speed is -6 m/s2 at t = 5 s. D. v'(5) = -3 m/s; the instantaneous rate of change in the train's speed is -3 m/s at t = 5 s.
