For 0≤t≤4, the position of a moving object is s(t)=3t2−12t+5 feet. Which statement correctly compares the object’s average velocity on [0,4] with its instantaneous velocity at t=2?
a) The average velocity on [0,4] is positive, while the instantaneous velocity at t=2 is negative.
b) Both the average velocity on [0,4] and the instantaneous velocity at t=2 are 0 ft/s.
c) The average velocity on [0,4] is positive, while the instantaneous velocity at t=2 is 0 ft/s.
d) The average velocity on [0,4] is 0 ft/s, while the instantaneous velocity at t=2 is positive.
