Question

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.

HINT

An illustration shows the horizontal initial position and
vertical final position of a uniform rod free to rotate in a
vertical plane around a pin passing through its left end. The rod
has mass *M*, length *L*, and its pivot point is
labeled "*O*." Another point, at the center of the rod, is
labeled "CG" and shown to be a distance *L*/2 from pivot
point *O*.

(a)

the rod's angular acceleration (in rad/s^{2})

rad/s^{2}

(b)

the tangential acceleration of the rod's center of mass (in
m/s^{2})

m/s^{2}

(c)

the tangential acceleration of the rod's free end (in
m/s^{2})

m/s^{2}

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 uniform rod of mass M and length L is pivoted at one end. The
rod is left to freely rotate under the influence of its own weight.
Find its angular acceleration α when it makes an angle 30° with the
vertical axis. Solve for M=1 Kg, L=1 m, take g=10 m s-2. Your
answer in X.X rad s-2. Hint: Find the center of mass for the rod,
and calculate the torque, then apply Newton as τ= Ι·α

A uniform thin rod of length 0.45 m and mass 6.5 kg can rotate
in a horizontal plane about a vertical axis through its center. The
rod is a rest when a 3.0-g bullet traveling in the horizontal plane
of the rod is fired into one end of the rod. As viewed from above,
the direction of the bullet velocity makes an angle of 60° with the
rod (see the figure). If the bullet lodges in the rod and the...

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...

A cylindrical rod of mass 0.82 kg and length 1.88 m is free to
rotate about a pivot fixed at one end. A ball with a mass of 3.2 kg
is attached to the other end of the rod. The rod-and ball system is
held in a horizontal position by a vertical force that acts 1.41 m
from the pivot. The force is then removed, and the rod-and-ball
swings down.
(a) What was the vertical force used to hold the...

A uniform rod of mass 250 g and length 75 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 25 g, are mounted in grooves along the
rod. Initially, the two beads are held by catches on opposite sides
of the rod’s center, 9 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 figure shows a thin rod, of length L = 2.10 m and
negligible mass, that can pivot about one end to rotate in a
vertical circle. A heavy ball of mass m = 7.10 kg is
attached to the other end. The rod is pulled aside to angle
θ0 = 5.3° and released with initial velocity v→0 = 0.
(a) What is the speed of the ball at the lowest
point? (b) Does the speed increase, decrease, or
remain...
