Question

9. A large toy yo–yo consisting of two uniform disks, each with radius r = 0.1 m and mass 0.5 kg, connected by a cylindrical piece with radius 1.0 cm and mass 0.1 kg is rolling down an incline plane (making an angle of 20◦ with respect to the horizontal). The yo–yo starts out from rest. What is the angular speed of the yo–yo after it travels through a height of 2.0 m?

Answer #1

A uniform disc of mass M=2.0 kg and radius R=0.45 m rolls
without slipping down an inclined plane of length L=40 m and slope
of 30°. The disk starts from rest at the top of the incline. Find
the angular velocity at the bottom of the incline.

1. A yo-yo consists of two solid disks, each of mass M and
radius 3R. The two disks are connected by a rod of radius R and
negligible mass.
a.) The moment of inertia of the yo-yo about its axis of
symmetry is of the form ???^2 where ? is a number. What is ??
b.) Draw the extended free body diagram for the yo-yo and use it
to write Newton's 2nd law in terms of the magnitude of the...

1. Read Section 11-3: we will consider the motion of a yo-yo
moving downward on its string.
(a) In terms of the yo-yo’s mass m, its moment of inertia about
the center-of-mass I, and the length of the string l, what is the
angular speed ? of a “sleeping” yo-yo that started from rest and
just finished rolling all the way down its string? You may assume
that kinetic friction between the yo-yo and the string has not yet
significantly...

A uniform, solid sphere of radius 3.00 cm and mass 2.00 kg
starts with a purely translational speed of 1.25 m/s at the top of
an inclined plane. The surface of the incline is 1.00 m long, and
is tilted at an angle of 25.0 ∘ with respect to the horizontal.
Assuming the sphere rolls without slipping down the incline,
calculate the sphere's final translational speed v 2 at the bottom
of the ramp.

A uniform, solid sphere of radius 4.50 cm and mass 2.25 kg
starts with a purely translational speed of 1.25 m/s at the top of
an inclined plane. The surface of the incline is 2.75 m long, and
is tilted at an angle of 22.0∘ with respect to the horizontal.
Assuming the sphere rolls without slipping down the incline,
calculate the sphere's final translational speed ?2 at the bottom
of the ramp.

A uniform, solid sphere of radius 3.50 cm and mass 1.25 kg
starts with a purely translational speed of 2.50 m/s at the top of
an inclined plane. The surface of the incline is 1.50 m long, and
is tilted at an angle of 28.0∘ with respect to the horizontal.
Assuming the sphere rolls without slipping down the incline,
calculate the sphere's final translational speed ?2 at the bottom
of the ramp. ?2= m/s

A solid, uniform sphere with a mass of 2.0 kg is rolling from
rest down an incline plane from the top of the plane. The incline
plane makes an angle of 20◦ with the horizontal and has a height of
2.0 m. At the bottom of the incline plane, the surface levels out
to a frictionless horizontal surface. A spring with a spring
constant of k is located 5.0 m down the horizontal surface. If the
spring is compressed by...

A hollow cylinder (hoop) of mass M and radius R starts rolling
without slipping (with negligible initial speed) from the top of an
inclined plane with angle theta. The cylinder is initially at a
height h from the bottom of the inclined plane. The coefficient of
friction is u. The moment of inertia of the hoop for the rolling
motion described is I= mR^2.
a) What is the magnitude of the net force and net torque acting
on the hoop?...

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...
