Question

a rod 2.5 m long with mass 10 kg can rotate freely about a horizontal axis through the end of the rod.

a bullet with mass 15 grams or 0.015 kg with a speed of 400 m/s strikes center of the rod in a direction perpendicular to the rod, and is embedded there.

What is the rod's angular speed after the bullet stops in the rod?

Answer #1

A uniform thin rod of length 0.56 m and mass 3.2 kg can rotate
in a horizontal plane about a vertical axis through its center. The
rod is at rest when a 3.5 g bullet traveling in the rotation plane
is fired into one end of the rod. As viewed from above, the
bullet's path makes angle θ = 60° with the rod. If the
bullet lodges in the rod and the angular velocity of the rod is
12.0 rad/s...

thick rod is rotating (without friction) about an axis that is
perpendicular to the rod and passes through its center. The
rotational inertia of the rod is 1.8 kg•m2. A 4.2-kg cat is
standing at the center of the rod. When the cat is at the center of
the rod, the angular speed is 4.8 rad/s. The cat then begins to
walk along the rod away from the center of the rod. The cat stops
at a distance of 0.4...

A cylindrical rod of length 2.0 m, radius 0.5 m, and mass 1.5 kg
has two spheres attached on its ends. The centers of the spheres
are 1.0 m from the center of the rod. The mass of each sphere is
0.66 kg. The rod is capable of rotating about an axis passing
through its center and perpendicular to the plane of the page, but
the set up is stationary to begin with. A small mass of value 0.19
kgmoving...

A uniform rod of mass 190 g and length 100 cm is free to rotate
in a horizontal plane around a fixed vertical axis through its
center, perpendicular to its length. Two small beads, each of mass
18 g, are mounted in grooves along the rod. Initially, the two
beads are held by catches on opposite sides of the rod's center, 18
cm from the axis of rotation. With the beads in this position, the
rod is rotating with an...

A 3.00-kg rod that is 2.60 m long is free to rotate in a
vertical plane about an axle that runs through the rod's center, is
perpendicular to the rod's length, and runs parallel to the floor.
A 1.00-kg block is attached to one end of the rod, and a 2.00-kg
block is attached to the other end. At some instant, the rod makes
an angle of 31.0 ? with the horizontal so that the blocks are in
the positions...

The uniform thin rod in the figure below has mass M =
2.00 kg and length L = 2.87 m and is free to rotate on a
frictionless pin. At the instant the rod is released from rest in
the horizontal position, find the magnitude of the rod's angular
acceleration, the tangential acceleration of the rod's center of
mass, and the tangential acceleration of the rod's free end.

An illustration shows the horizontal initial position and
vertical final position...

A 3.00-kg rod that is 1.40 m long is free to rotate in a
vertical plane about an axle that runs through the rod's center, is
perpendicular to the rod's length, and runs parallel to the floor.
A 1.00-kg block is attached to one end of the rod, and a 2.00-kg
block is attached to the other end. At some instant, the rod makes
an angle of 37.0 ? with the horizontal so that the blocks are in
the positions...

A 415 gram, 1.6 meter long wooden rod is pivoted at its center.
A 4 gram bullet traveling a 188 m/s strikes it perpendicular to its
length and half way between the center and the end. If the bullet
exits with half its entrance velocity, what is the angular speed of
the rod after the bullet leaves to the nearest hundredth of a
radian/s? answer is 1.70
In this problem use 6x1024 kg and 6.4x106 m for the mass and...

Two 2.4 kg balls are attached to the ends of a thin rod of
negligible mass, 54 cm in length. The rod is free to rotate in a
vertical plane about a horizontal axis through its center. With the
rod initially horizontal as shown, a 0.33 kg wad of wet putty drops
onto one of the balls with a speed of 3.7 m/sec and sticks to
it.
1)What is the ratio of
the magnitude of angular momentum of the entire...

A rod with a length of 80 cm is pivoted about a horizontal axis
through its center (rod's mass is negligable). A black mouse with a
mass of 0.510 kg clings to one end of the stick, and a
brown rat with a mass of 0.211 kg clings to the other
end. The system is released from rest with the rod horizontal.
Part A
If black mouse and brown rat can hold on, Find their velocities
as the rod swings through a...
