Question

A)The sphere reaches the bottom first.

B) The cylinder reaches the bottom first.

C) They reach the bottom together.

Answer #1

A hollow sphere and a solid sphere each have the same mass and
radius. They are released simultaneously from rest and allowed to
roll without slipping down a ramp. Which one reaches the bottom
first? Group of answer choices
the solid sphere
You can't determine which is first unless you know the mass.
You can't determine which is first unless you know the
radius.
They reach the bottom at the same time.
the hollow sphere

Three small objects, a cube, a solid sphere, and a solid
cylinder, are released simultaneously from the top of three
inclines planes with inclination angles of 15°, 30°, and 60°
respectively. The horizontal distances between the top and bottom
of the inclines are the same. Assume that the cube slides down
without friction while the sphere and cylinder roll down without
slipping. Rank the order in which the objects reach the bottom of
the inclined planes from first to last?...

A solid, uniform sphere of mass 2.0 kg and radius 1.7m rolls
without slipping down an inclined plane of height 7.0m . What is
the angular velocity of the sphere at the bottom of the inclined
plane? a) 5.8 rad/s b) 11.0 rad/s c) 7.0 rad/s d) 9.9 rad/s

A solid sphere ( of mass 2.50 kg and radius 10.0 cm) starts
rolling without slipping on an inclined plane (angle of inclination
30 deg). Find the speed of its center of mass when it has traveled
down 2.00 m along with the inclination.
Groups of choices:
a. 3.13 m/s
b. 4.43 m/s
c. 3.74 m/s
d. 6.26 m/s

A spherical shell, a solid sphere and a solid cylinder are
released from rest at the top of and inclined plane, in what order
will they reach the bottom. All objects have the same mass and
radius.

A solid cylinder of radius 25cm is released from rest at the top
of a smooth 4degree incline of height h=5m. At the same time and
from the same position, a hollow sphere of radius 25 cm is also
released from res. Both objects roll without slipping and both
objects have a mass of 75g.
How long did it take for the faster of the two objects to reach
the bottom of the hill?

A solid brass cylinder and a solid wood cylinder have the same
radius and mass (the wood cylinder is longer). Released together
from rest, they roll down an incline. (a) Which cylinder reaches
the bottom first, or do the tie? (b) The wood cylinder is then
shortened to match the length of the brass cylinder, and the brass
cylinder is drilled out along its long (central) axis to match the
mass of the wood cylinder. Which cylinder now wins the...

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.
?2=__________ m/s
