The record distance in the sport of throwing cowpats is 81.1 m. This record toss was set by Steve Urner of the United States in 1981. Assume the initial launch angle was 45° and neglect air resistance.
(a) Determine the initial speed of the projectile. m/s
(b) Determine the total time the projectile was in flight? s
(c) Qualitatively, how would the answers change if the launch angle were greater than 45°? Explain.
