Suppose that the distance travelled by an object at time!\" is given by f(1') = 51'2 31'. (a) Find the average velocity between 1' = 1 and 1' = 3. Enter a number only: |:| (b) In this part we'll find the instantaneous velocity (IROC) at 2' = 2 by using the method of small intervals. Complete each step below. Enter numbers only into the blanks. Keep ALL decimal places in all calculations and also in your answers. (i) Find the AROC betweent = 1.9 and! = 2: |:| (ii) Find the AROC between!\" = 1.99 and!\" = 2: |:| (iii) Find the AROC betweenr = 1.999 and 1' = 2: |:| (iv) Based on your previous three calculations, what is your estimate for the IROC at t = 2?
