Physics

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 25.0 m/s at an angle of 57.5° above the ground, what is the "hang time"?

asked by kelly
  1. The hang time is twice the time it takes for the vertical velocity component (which in initially 25.0 sin 57.5 m/s) to reach zero. That equals twice the time it takes to reach its highest elevation.

    T = 2 Vo sin 57.5/g

    g is the acceleration of gravity.
