In honor of NFL Super Bowl LIV this past Sunday, here’s a football physics question to tease your brain!
In U.S. football, after a touchdown the team has the opportunity to earn one more point by kicking the ball over the bar between the goal posts. The bar is 3.048 meters above the ground, and the ball is kicked from ground level, 10.9728 meters horizontally from the bar.
If the ball is kicked at 37 degrees above the horizontal, what must its initial speed be if it is to just clear the bar? Express your answer in meters per second (m/s).
