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 10.0 ft above the ground, and the ball is kicked from ground level, 36.0 ft horizontally from the bar (the figure (Figure 1)). Football regulations are stated in English units, but convert to Sl units for this problem. Part B If the ball is kicked at 38 ° above the horizontal, what must its initial speed be if it to just clear the bar? Express your answer in m/s.
