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 46.0° 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.)
(b) Does the ball approach the crossbar (and cross above or beneath it) while still rising or while falling?

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 22.4 m/s at an angle of 47.0° to the
horizontal. (a) By how much does the ball clear or fall short

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 20.2 m/s at an angle of 51.0° to the
horizontal.

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 21.7 m/s at an angle of 48.5° to the
horizontal.

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 23.4 m/s at an angle of 48.0° to the
horizontal.

A placekicker is about to kick a field goal. The ball is 25.3 m
from the goalpost. The ball is kicked with an initial velocity of
20.8 m/s at an angle θ above the ground. Between what two
angles, θ1 and θ2, will the
ball clear the 2.86-m-high crossbar? Give your answers as
(a) the smaller angle and (b) the
larger angle. (Hint: The following trigonometric identities may
be useful:
sec θ = 1/(cos θ) and
sec2θ = 1 +...

A football kicker can give the ball an initial speed of 25.0
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 50.0
m in front of goalposts whose horizontal bar is 3.44 m above the
ground? When doing this, you may want to research some trig
identities to get a formula involving only tangent functions. Also,
since there are two values of angle...

Data from the National Football League (NFL) from a recent
season reported the number of yards gained by each of the league's
wide receivers. The data in this Excel file
nfl_receiver_yds_webassign shows the yards gained by each wide
receiver in the NFL who gained 50 or more yards during the season.
The number of yards gained is right-skewed and therefore a normal
model is NOT a good model for the data. However, the square root of
the number of yards...

Why do casinos place a point spread on football betting
opportunities? Also, why would a point spread change from when the
game is originally posted and before the game officially starts?
Please provide data and examples.

You place a mass m = 40 g on a book and slowly increase the
angle e that the book makes with the horizontal. At a critical
angle theta_c = 42°, the mass starts to slide so you hold the angle
constant. The mass takes 0.75 s to slide a distance of 17 cm to the
edge of the book. Assume that the values of mu_s and mu_k, are
uniform all over the book.
c) What is the value of...

A 6.00-kg point mass and a 15.0-kg point mass are held in
place 1.00 m apart. A point particle of mass m = 1.00 kg is
released from a point between the two masses such that the net
gravitational force on this particle is zero. Call the line
connecting all the masses x-axis.
a. Find the center of mass of this system.
b. Find the exact position of this point mass.
c. Calculate potential energy of this system.
d. If...
