3. [6pts] A ball is thrown into the air. The height of the ball is given by the following equation, where H(t) represents the ball's height in feet above the ground t seconds after it was thrown: H (t) - -2t2 + 50t + 7 3.(a) Find the average rate of change in the height of the ball from t = 0 to t = 3 seconds. 3.(b) Find H'(t) and H"(t). What do these represent in terms of the ball's motion? 3.(c) Using the limit definition, find the instantaneous rate of change in the ball's height when t - 2. crm2313-unit-5-....pdf Failed - Insufficient permiss..
