Question

To win the game, a place kicker must kick a football from a point 45 m (49.212 yd) from the goal, and the ball must clear the crossbar, which is 3.05 m high. When kicked, the ball leaves the ground with a speed of 24 m/s at an angle of 32.6 ◦ from the horizontal. The acceleration of gravity is 9.8 m/s 2 . By how much vertical distance does the ball clear the crossbar? Answer in units of m.

Answer #1

To win the game, a place kicker must kick a football from a
point 45 m (49.212 yd) from the goal, and the ball must clear the
crossbar, which is 3.05 m high. When kicked, the ball leaves the
ground with a speed of 24 m/s at an angle of 32.6 ◦ from the
horizontal. The acceleration of gravity is 9.8 m/s 2 . By how much
vertical distance does the ball clear the crossbar? Answer in units
of m.

19. A place kicker must kick a football from a point 35 m (about
38 yd) from the goal, and the ball must clear the crossbar, which
is 3.05 m high. When kicked, the ball leaves the ground with a
speed of 23 m/s at an angle of 51◦ to the horizontal. By how much
does the ball clear or fall short of clearing the crossbar? The
acceleration of gravity is 9.8 m/s 2 . Answer in units of m....

20. A place kicker must kick a football from a point 35 m (about
38 yd) from the goal, and the ball must clear the crossbar, which
is 3.05 m high. When kicked, the ball leaves the ground with a
speed of 23 m/s at an angle of 51◦ to the horizontal. To determine
if the ball approaches the crossbar while still rising or while
falling, what is its vertical velocity at the crossbar? Answer in
units of m/s.

A place kicker must kick a football from a point 34.2 m from a
goal. As a result of the kick, the ball must clear the crossbar,
which is 3.05 m high. When kicked the ball leaves the ground with a
speed of 20.5 m/s at an angle of 53° to the horizontal.

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 20.6 m/s at an angle of 45.0° to the
horizontal.

A football kicker is practicing a field goal ick. THe football
(on the ground before it starts) has a initial velocity of 24 m/s
at an angle of 40 degrees above the horizontal. The ball flies
between two goal posts and hits the right cross bar. The cross bar
is 10 ft above the ground. Ignore air resistance.
a) What are the x and y components of the intial velocity b)
What is the total flight time of the football...

A soccer player takes a free kick from a spot that is 26 m from
the goal. The ball leaves his foot at an angle of 35 ∘, and it
eventually hits the crossbar of the goal, which is 2.4 m from the
ground. At what speed did the ball leave his foot?

A football is kicked from ground level with an initial velocity
of 24.2 m/s at angle of 51.0° above the horizontal. How long, in
seconds, is the football in the air before it hits the ground?
Ignore air resistance.
