The punter on a football team tries to kick a football so that it stays in the air for a long "hang time." If the ball is kicked with an initial velocity of 25.2 m/s at an angle of 58.5° above the ground, what is the "hang time"?

Answer 1

hf=hi+vivertical*t-4.9t^2
0=0+25.2sin58.5 -4.9t^2
solve for time in the air, t.
