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 24.2 m/s at an angle of 58.5° above the ground, what is the "hang time"?
1 answer
Double the time it takes to reach zero vertical velocity component. Half the time is spenty rising to that height; the other half is spent coming back down.
