the level floor is

Answer #1

A disc with a radius of 0.50 m starts from rest and rolls down
an incline. The disc starts from a point that is 8.0 m above the
bottom of the incline. What is the translational speed of the disc
at the bottom of the incline? Enter the result in scientific
E-notation.

A sphere of radius r=34.5 cm and mass m= 1.80kg starts from rest
and rolls without slipping down a 30.0 degree incline that is 10.0
m long. calculate the translational and rotational speed when it
reaches the bottom.

A solid cylinder rolls without slipping down a 30° incline that
is 5.0 m long. The cylinder's mass is 3.0 kg and its diameter is 44
cmcm . The cylinder starts from rest at the top of the ramp.
1) What is the linear speed of the center of the cylinder when
it reaches the bottom of the ramp.
2) What is the angular speed of the cylinder about its center at
the bottom of the ramp.
3) What is...

A solid sphere of uniform density starts from rest and rolls
without slipping a distance of d = 4.4 m down a
θ = 22°incline. The sphere has a
mass M = 4.3 kg and a radius R
= 0.28 m.
1)Of the total kinetic energy of the sphere, what fraction is
translational?
KE
tran/KEtotal =
2)What is the translational kinetic energy of the sphere when it
reaches the bottom of the incline?
KE tran =
3)What is the translational speed...

A sphere of mass M, radius r, and rotational inertia I is
released from rest at the top of an inclined plane of height h as
shown above. (diagram not shown)
If the plane has friction so that the sphere rolls without
slipping, what is the speed vcm of the center of mass at the bottom
of the incline?

A very thin circular hoop of mass m and radius
r rolls without slipping down a ramp inclined at an angle
θ with the horizontal, as shown in the figure.
What is the acceleration a of the center of the
hoop?

A solid cylinder rolls without slipping down an incline starting
from rest. At the same time a box starts from rest at the same
altitude and slides down the same incline with negligible friction.
Which arrives at the bottom first?
A. It is impossible to determine.
B. the box
C. the cylinder
D. Both arrive at the same time.

A solid cylinder starts from rest at the top of an incline of
height h = 0.7 m and rolls down without slipping. Ignoring
friction, determine the speed at the bottom of the incline. Draw
and label a figure.

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 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?...
