[I] For the following position functions 3; : s (t) , an object is moving along a straight line, where t is in seconds and 5 is in meters. Find a. the simplified expression for the average velocity from t : 2 to t : 2 l h; b. the average velocity between t : 2 and t : 2 | h, where (i) h : 0.1, (ii) h : 0.01, (iii) h : 0.001, and (iv) h : 0.0001; and 0. use the answer from a. to estimate the instantaneous velocity at t : 2 second. w 36. 3(25) : t2 2t
