A football weights 0.91 lbf and approximates an ellipsoid 6 in diameter and 12 in long (Table 7.3). It is thrown upward at a 45° angle with an initial velocity of 80 ft/s. Neglect spin and lift. Assuming turbulent flow, estimate the horizontal distance traveled,
(a) Neglecting drag and
(b) Accounting for drag with a numerical (computer) model. Fig. P7.71
