A football player releases a ball with the initial conditions shown in the figure. Determine the radius of curvature of the trajectory at times t- 1.2 sec andt- 2.5 sec, where t- 0 is the time of release from the quarterback's hand. For each case, compute the time rate of change of the speed. 86 ft/sec = 40 Answers: For t- 1.2 sec, p- i ft. v = ft/sec2 For t- 2.5 sec, p- i ft, v = i ft/sec?
