A fireman 54.0 m away from a burning building directs a stream of water from a ground-level fire hose at an angle of 20.0° above the horizontal. If the speed of the stream as it leaves the hose is 40.0 m/s, at what height will the stream of water strike the building? 9.6 m (above ground level) A placekicker 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 22.0 m/s at an angle of 46.0° to the horizontal, (0) By how much does the ball clear or fall short of clearing the crossbar? (Enter a negative answer if it falls short) (b) Does the ball approach the crossbar while still rising or while falling?
