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 23.0 m/s at an angle of 58.5° above the ground, what is the "hang time"?

  • physics - ,

    The hang time is twice the time it takes for the vertical velocity component (which in initially 23.0 sin 58.5 m/s) to reach zero. That equals twice the time it takes to reach its highest elevation.

    T = 2 Vo sin 58.5/g

    g is the acceleration of gravity.
