Question

At the Dallas cowboys stadium, the minimum clearance height between the football field and the giantic video screens that hang over the field is only 90ft (27.43 m). In the first game played at the cowboys stadium on August 21,2009, a punters kick hit the video screen.

A. What minimum initial vertical velocity would a football need to have to hit the video screens if it were kicked from a height 1m above the playing field surface? Assume that air resistance does not affect the flight of the football.

B. If the video screens were not in the way, what would hang time for a football kicked 27.43 m high? Again, assume that air resistance does not affect the flight of the football and that the ball is 1m above the playing field when it is kicked.
