Question

A football kicker can give the ball an initial speed of 29 m/s He is 35 m from the goalpost which has crossbar 3.40 m high. (a) What is the smallest angle of elevation that he can kick the football and score a field goal? (b) What is the largest angle of elevation that he can kick the football and score field goal?

A football kicker can give the ball an initial speed of 29 m/s He is 35 m from the goalpost which has crossbar 3.40 m high. (a) What is the smallest angle of elevation that he can kick the football and score a field goal? (b) What is the largest angle of elevation that he can kick the football and score field goal?



Answers

A football kicker can give the ball an initial speed of 25 $\mathrm{m} / \mathrm{s}$ . What are the (a) least and (b) greatest elevation angles at
which he can kick the ball to score a field goal from a point 50 $\mathrm{m}$ in
front of goalposts whose horizontal bar is 3.44 $\mathrm{m}$ above the ground?
