Question

The record distance in the sport of throwing cowpats is 81.1 m. Assume the initial launch angle was 45 degrees and neglect air resistance.

Determine the Initial Speed of the projectile and the total flight time the projectile was in.

Total Flight Time:

Also, qualitatively, how would the answers change if the launch angle were greater than 45 degrees? Explain.

Explanation / Answer

Let the speed be V Range = V^2sin(2a)/g => 81.1 = v^2sin90/9.8 => v = square root(81.1*9.8) = 28.19 Time of flight we have Vertical velocity = 28.19/square root(2) = 19.93 Time to go up and down = 2*19.93/9.8 = 4.06
