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. Assuming the initial launch angle was 45° and neglecting air resistance, determine (a) the initialspeed of the projectile and (b) the total time interval the projectile was in flight. (c) How would the answers change if the range were the same but the launch angle were greater than 45°? Explain.

During the siege of Constantinople that led to its conquest by the Ottomans in 1453, the
Hungarian engineer Orban built a set of bombards (primitive cannon) to throw enormous stones
at the city to breach its walls. The largest of these could throw a 300 kg stone a distance x = 2
km. Assume that the stone was launched at an angle of 0 = 45 degrees above the horizontal; in
the absence of air resistance, this gives the largest range.
a) What speed did the stone have to be launched at to achieve this range?
b) How long was the ball in the air?
c) How fast was the ball traveling at the apex of its flight?
