Explanation / Answer

Solution:

Concept -
If the ball was thrown horizontally, the player #2 could not have caught the ball at the same level that it was thrown. So, player #1 must have thrown the ball at angle of above horizontal .

Vo = 7.1 m/s
D = 4.4 m
g = 9.81 m/s^2

Solve for angle:

2 = sin-1 { [D * g] / V^2 }

=> = 29.4495o (Approx.)
