On another planet, the height of a dropped object is given by h(t) = 30 - 2.2t2 , where h is in feet and t is in seconds. a. Find the average velocity of the object on the intervals given in the table below. Show work on your paper. Include units in your answer and do NOT round your answers. time interval average velocity t=1.9 to t-2 t-1.99 to t=2 t=1.999 to t=2 A b. Use your answers from part (a) to estimate the instantaneous velocity at t=2 seconds. Write this estimate in the answer box, including units
