A door with mass M= 3.00 kg and width L=2.00m is hinged at one side so that it can rotate without friction about a vertical axis. A heavy bullet embeds in the 3L/4 of the door after it is fired as shown. The mass of the bullet is m=0.200kg and the initial speed of the bullet is speed 410 m/s . Part A Part complete What is the angular speed of the bullet and the door after the bullet embeds...

Problem: A pulley, consists of a disk of radius R=0.2 m and mass M= 50 kg is mounted on a nearly frictionless axle. A string is wrapped lightly around the pulley, and you pull on the string with a constant force, F = 100 N. If the pulley starts from rest, what is the angular speed at a time At = 1 s later? Assume that the string does not slip on the pulley. Note: Moment of inertia of a...

A thin stick of mass 0.5 kg and length
L = 0.8 m
is attached to the rim of a metal disk of mass
M = 5.0 kg
and radius
R = 0.4 m.
The stick is free to rotate around a horizontal axis through its
other end (see the following figure).
(a)
If the combination is released with the stick horizontal, what
is the speed (in m/s) of the center of the disk when the stick is
vertical?

A 25. As shown in figure 9, a ball of mass M is hanging from a rope to make a pendulum. A 10 g bullet strikes the ball with a speed v = 308 m/s. The center of mass of the ball + bullet rises a vertical distance of h = 12 cm. Assuming that the bullet remains embedded, calculate the mass M of the ball. (Ans: 2.0 kg) A27. Block A (mass = 2.0 kg, velocity = 50 m/s)...

A uniform thin rod of length 0.500 m and mass 4.00 kg is attached to a pivot at one end. The other end of the rod is attached to a uniform sphere with a mass of 2.00 kg and a radius of 0.100 m. The rod and sphere initially hang vertically. A bullet with a mass of 5.00 g is fired horizontally at a speed of 200 m/s into the center of the sphere. The bullet embeds itself in the...

A 2.0 m measuring stick of mass 0.165 kg is resting on a table. A mass of 0.500 kg is attached to the stick at a distance of 74.0 cm from the center. Both the stick and the table surface are frictionless. The stick rotates with an angular speed of 5.40 rad/s. a)If the stick is pivoted about an axis perpendicular to the table and passing through its center, what is the angular momentum of the system? b)If the stick...

1) A ballistic pendulum consists of a 3.60 kg wooden block on the end of a long string. From the pivot point to the center‐of‐mass of the block is a distance of 2.80 m. With the pendulum hanging straight down, a rifle bullet of 28.0 g mass moving with a speed of 210 m/s embeds itself into the wood. To what maximum angle does the pendulum (with embedded bullet) swing upward? 2) The thorium‐228 nucleus decays by emitting an alpha...

A stick of length 1.5 m and mass 8.0 kg is free to rotate about a horizontal axis through the center. Small bodies of masses 7.0 and 4.0 kg are attached to its two ends. The stick is released from the horizontal position. What is the angular velocity of the stick (in rad/s) when it swings through the vertical? (Enter the magnitude.)

A stick of length 1.5 m and mass 9.0 kg is free to rotate about
a horizontal axis through the center. Small bodies of masses 8.0
and 2.0 kg are attached to its two ends (see the following figure).
The stick is released from the horizontal position. What is the
angular velocity of the stick (in rad/s) when it swings through the
vertical? (Enter the magnitude.)

A uniform slender bar of mass M = 3.2 kg and length L = 1.78 m is translating on the smooth horizontal x-y plane with a velocity vm= 1.80 m/s when a particle of mass m = 0.36 kg traveling with a velocity Vm=5.52 m/s as shown strikes and becomes embedded in the bar. Determine the final linear velocity of the center of mass of the system and the angular velocity of the bar with its embedded particle. 3L 4...
