Suppose the velocity of an object at time t is given by v (t) = 12 - 2t² where t is in seconds and v (t) is in feet/sec . (a) Find the displacement of the object from t = 0 seconds to t = 5 seconds. Include units in your answer. (b) Find the total distance the object travels from t = 0 seconds to t = 5 seconds,. Include units in your answer.
