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.

Answer parts B and C

 

**Transcription for Educational Website** --- ### Context In U.S. football, after a touchdown, the team has the opportunity to earn one extra point by kicking the ball over the bar between the goal posts. The bar is positioned 10.0 feet above the ground, and the ball is kicked from ground level, 36.0 feet horizontally from the bar (refer to Figure 1). Football regulations are stated in English units, but convert to SI units for this problem. ### Figure Explanation **Figure 1**: The diagram illustrates a football kick scenario. The ball is positioned on the ground, and a vector indicates the initial path of the ball at an angle. The goal post is shown with the crossbar at 10.0 feet high, located 36.0 feet horizontally from the kick point. --- ### Problems and Answers #### Part B - **Question**: If the ball is kicked at 38° above the horizontal, what must its initial speed be to just clear the bar? Express your answer in meters per second (m/s). - **Provided Answer**: \( v_0 = 12.56 \, \text{m/s} \) - **Feedback**: Incorrect; Try Again. 4 attempts remaining. #### Part C - **Question**: If the ball is kicked at 38° above the horizontal, what must its initial speed be to just clear the bar? Express your answer in kilometers per hour (km/h). - **Provided Answer**: \( v_0 = 45.21 \, \text{km/h} \) - **Feedback**: Incorrect; Try Again. 5 attempts remaining. --- *Note: Users are advised to carefully check calculations and unit conversions when solving problems.*
