Question

A hollow spherical shell with mass 2.45 kg rolls without slipping down a slope that makes an angle of 30.0 degrees with the horizontal.

Find the minimum coefficient of friction μ needed to prevent the spherical shell from slipping as it rolls down the slope.

Answer #1

A hollow spherical shell with mass 2.35 kg rolls without
slipping down a slope that makes an angle of 35.0 ? with the
horizontal. Find the magnitude of the acceleration acm of the
center of mass of the spherical shell. Take the free-fall
acceleration to be g = 9.80 m/s2 .Find the magnitude of the
frictional force acting on the spherical shell. Take the free-fall
acceleration to be g = 9.80 m/s2 .

A spherical shell of mass M is released from rest and rolls
without slipping down a 40.00 sloped hill. Determine the
center of mass speed of the object when the ball has rolled 6.00
meters along the hill. Ignore any thickness of the shell. Please
show work and possible thoughts

A hollow sphere (mass 8.8 kg, radius 54.8 cm) is rolling without
slipping along a horizontal surface, so its center of mass is
moving at speed vo. It now comes to an incline that makes an angle
56o with the horizontal, and it rolls without slipping up the
incline until it comes to a complete stop. Find a, the magnitude of
the linear acceleration of the ball as it travels up the incline,
in m/s2.

A uniform cylinder of mass M and radius R rolls without slipping
down a slope of angle theeta to the horizontal. The cylinder is
connected to a spring constant K while the other end of the spring
is connected to a rigid support at P. The cylinder is released when
the spring is unstrectched. The maximum displacement of cylinder is
?

A basketball starts from rest and rolls without slipping down a
hill. The radius of the basketball is 0.23 m, and its 0.625 kg mass
is evenly distributed in its thin shell. The hill is 50 m long and

A hollow sphere of radius 16cm and mass 10kg stars from rest and
rolls without slipping a distance d=6.5m down a roof that is
inclined at an angle of 36°.
a. What is the angular speed of the hollow sphere about its
center as it leaves the roof?
b. The roof’s edge is at a height of 4.5m. How far horizontally
from the roof’s edge does the hollow sphere hit the level
ground?

A hollow sphere (spherical shell) is rolling down an incline.
The incline has an angle theta, the sphere has a radius of R, and
mass M. Please calculate the acceleration of the sphere has it
rolls down the hill.

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.

A 0.38 kg playground ball with a 12.0 cm radius rolls without
slipping down a pool slide from a vertical distance h1= 2.2 m above
the bottom of the slide and then falls an additional h2= 0.40 m
vertical distance into the water. What will be the magnitude of the
ball's translational velocity when it hits the water? Since the
ball is air-filled, assume it approximates a hollow, thin spherical
shell. Also, assume that its rate of rotation remains constant...
