Problem: A football kicker can give the ball an initial speed of 27 m/s. He is 48 m from the goalpost which has a crossbar 2.72 m high.
Part A: What is the smallest angle of elevation that he can kick the football and score a field goal?
Part B: What is the largest angle of elevation that he can kick the football and score a field goal?
Please show your results in detailed calculations.
