The record distance in the sport of throwing cowpats is 81.1m. Assuming the initial launch angle was 45 degrees, and neglecting air resistance, determine (a) the initial speed of the projectile and (b) the total time the projectile was in flight? Thanks.

Initial speed is #28,19m//s# and total time is #4,07s#.

Explanation:

We may divide the motion into parts A - B and B - C as shown in my sketch below. And then consider horizontal and vertical components in each part, together with laws of projectile motion and equations of motion for constant acceleration, to eventually obtain the answers.
