ITa ball is thrown into the air with an initial velocity of 48 ft/s, its height in feet after t seconds is given by y = 48t - 16t2. (a) Find the average velocity of the ball (in ft/s) for the time interval beginning at t = 2 and lasting for each of the following. (i) 0.5 seconds -24 ft/s (ii) 0.1 seconds -17.6 ft/s (iii) 0.05 seconds x ft/s (iv) 0.01 seconds -16.16 ft/s (D) Use your answers from part (a) to estimate the instantaneous velocity (in ft/s) when t - . -16 ft/s
