A kicker kicks a football off the ground when he is located 30 meters away (measured horizontally) from the goalposts. He kicks it at an angle of 30◦ above the horizontal. With what minimum speed (in m/s) does he need to kick the ball in order to get it over the crossbar (3 meters off the ground)?
The answer should be 20.3 m/s

To win the big game, the field goal kicker takes the field and attempts to kick a field goal from 50.0 meters away from the goalposts, whose crossbar is 3.05 m above the ground. He kicks the football at an angle of 30o above the horizontal with an initial speed of 25 m/s. a) Assuming the football is aimed correctly between the goalposts, is the field goal attempt good? (b) If so, by how much does it clear the bar?...

If the kicker typically kicks the ball with a launch angle of 36.6º, what minimum launch velocity does the kicker need in order for the football to clear the crossbeam of the goalposts 3 meters above the ground?
The place kicker on a football team kicks a ball from ground level with an initial speed of 8.60 m/s at an angle of 31.0° above the horizontal. (a) How long is the ball in the air, in seconds, before it lands on the ground again? Find in seconds. You may neglect air resistance. (b) How far does it travel in the horizontal direction?
A football kicker can give the ball an initial speed of 31 m/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 48 m in front of goalposts whose horizontal bar is 3.44 m above the ground?
A football kicker can give the ball an initial speed of 35 m/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 43 m in front of goalposts whose horizontal bar is 3.44 m above the ground?

A place-kicker must kick a football from a point 36.0 m (about 40 yards) from the goal. Half the crowd hopes the ball will clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 21.2 m/s at an angle of 49.0° to the horizontal. (a) By how much does the ball clear or fall short (vertically) of clearing the crossbar? (Enter a negative answer if it falls short.)
