Question

A string is attached to the rim of a small hoop of radius r =
8.00×10^{−2} m and mass m = 0.180 kg and then wrapped
several times around the rim. If the free end of the string is held
in place and the hoop is released from rest and allowed to drop, as
shown in the figure (Figure 1), calculate the angular speed and the
translational speed of the rotating hoop after it has descended h =
0.750 m . Use g = 9.80 m/s2 for the acceleration due to
gravity.

1. What is the translational speed of the rotating hoop after it has descended a distance 0.750 m ?

Express your answer in meters per second.

Answer #1

Thanks you.

A string is attached to the rim of a small hoop of radius r =
8.00×10−2 m and mass m = 0.180 kg and then wrapped several times
around the rim. If the free end of the string is held in place and
the hoop is released from rest and allowed to drop. calculate the
angular speed and the translational speed of the rotating hoop
after it has descended h = 0.750 m . Use g = 9.80 m/s2 for...

A green hoop with mass mh = 2.4 kg and radius Rh = 0.14 m hangs
from a string that goes over a blue solid disk pulley with mass md
= 2.3 kg and radius Rd = 0.08 m. The other end of the string is
attached to an orange block on a flat horizontal surface that
slides without friction and has mass m = 3.6 kg (see Figure 1). The
system is released from rest.

An green hoop with mass
mh = 2.7 kg and radius Rh = 0.15 m
hangs from a string that goes over a blue solid disk pulley with mass
md = 2.1 kg and radius Rd = 0.09 m.
The other end of the string is attached to a massless axel through
the center of an orange sphere on a flat horizontal surface that
rolls without slipping and has mass ms = 3.7 kg and
radius Rs = 0.19 m. The system is released from
rest.

A solid uniform disk of mass M = 9.6 kg and radius R = 21 cm
rests with its flat surface on a frictionless table (i.e., the axis
of the cylinder is perpendicular to the table.) The diagram shows a
top view. A string is wrapped around the rim of the disk and a
constant force of F = 10.8 N is applied to the string. The string
does not slip on the rim.

a) At a certain instant, a rotating turbine wheel of radius R
has angular speed ω (measured in rad/s). What must be the magnitude
α of its angular acceleration (measured in rad/s2) at this instant
if the acceleration vector a⃗ of a point on the rim of the wheel
makes an angle of exactly 30∘ with the velocity vector v⃗ of that
point? Express your answer in terms of some or all of the variables
R and ω.

A solid sphere of mass, M, and radius, R, is
rigidly attached to a strong thin rod of radius r that
passes through the sphere at a distance of R/2. A string
wrapped around the rod pulls with tension T. The rod's
moment of inertia is negligible.
(a) Find an expression for the sphere's angular
acceleration.
(b) If the sphere has a mass of 5.5 kg and a radius of 25 cm,
how much tension must be applied to the...

A small, solid cylinder with mass = 20 kg and radius = 0.10 m
starts from rest and rotates without friction about a fixed axis
through its center of mass. A string is wrapped around the
circumference of the cylinder and pulled using a constant force F.
The resulting angular acceleration of the cylinder is 5.0 rad/s2.
What's the angular velocity after 4.0 s, in radians per second?
(The moment of inertia of the cylinder is 1 half M R...

A solid cylinder has a mass of 100 kg and radius 0.225m. The
cylinder is attached to a frictionless horizontal axle. A long
(light weight) cable is wrapped around the cylinder. Attached to
the end of the cable is a 1.50 kg mass. The system is initially
stationary. The hanging mass is then released. The mass pulls on
the cable as it falls and this causes the cylinder to rotate.
a) What is the velocity of the hanging mass after...

A small, solid cylinder with mass = 20 kg and radius = 0.10 m
starts from rest and rotates without friction about a fixed axis
through its center of mass. A string is wrapped around the
circumference of the cylinder and pulled using a constant force
F. The resulting angular acceleration of the cylinder is
5.0 rad/s2. (The moment of inertia of the cylinder is
1/2 MR^2.)

2. What's the angular velocity after...

An object with a mass of m = 5.5 kg is attached to the free end
of a light string wrapped around a reel of radius R = 0.260 m and
mass of M = 3.00 kg. The reel is a solid disk, free to rotate in a
vertical plane about the horizontal axis passing through its center
as shown in the figure below. The suspended object is released from
rest 6.40 m above the floor. (a) Determine the tension...
