Answer #1

A sphere is released from rest at the top of an inclined plane.
What is the speed of the sphere at a distance 6.0 m below its
starting point. Assume that the sphere rolls without slipping.

A hoop and a disk, both of 0.88- m radius and 4.0- kg mass, are
released from the top of an inclined plane 3.3 m high and 8.1 m
long. What is the speed of each when it reaches the bottom? Assume
that they both roll without slipping. What is the speed of the
hoop? What is the speed of the disk?

A hoop and a disk, both of 0.50- m radius and 4.0- kg mass, are
released from the top of an inclined plane 2.9 m high and 8.7 m
long. What is the speed of each when it reaches the bottom? Assume
that they both roll without slipping. What is the speed of the
hoop? What is the speed of the disk?

3.. A 1800kg car is placed on an inclined plane with an angle
of 37° to the horizontal. The inclined plane is 85.0-m long. The
coefficient of friction is .22.
a) How long does it take for the car to reach the bottom of
the inclined plane after it is released from rest?
b) What would the final velocity be?

A sphere is released from the top of a rough inclined plane. The
friction is sufficient so that the sphere rolls without slipping.
Mass of the sphere is M and radius is R. The height of the center
of the sphere from ground is h. Find the speed of the center of the
sphere as it reaches the bottom of the sphere.

A block with a mass of 12.0 kg is initially at rest at the top
of a plane that is inclined at an angle of 30.0° above the
horizontal. The block slides down the plane and is traveling with a
speed of 1.50 m/s when it reaches the bottom. If the plane is 0.750
m long, what is the coefficient of kinetic friction between the
block and the plane? please explain each step.

a ball starting from rest at the top of an inclined
plane accelerates at 2m/s2 and reaches the bottom of the plane in 2
seconds. What is the length of the plane?

A 5.000 kg mass starts from rest and slides down on an inclined
plane that is 5 degrees above the horizontal. If friction causes
the body to accelerate at 20%, determine magnitude and direction of
friction force.

A
particle of mass 2kg rest on the surface of a smooth plane inclined
at an angle 30 degrees to the horizontal. It is connected by a
light inelastic string passing over a smooth pulley at the top of
the plane to a particle of mass 5.8kg which is hanging freely.
After the system is released from reat its acceleration ( in m/s)
is?
b) Calculate the force (in N) acting on the pulley due to the
string, if the...

A hoop with a mass of 2.95 kg starts from rest at the top of a
ramp. The ramp is 4.6 m long and 1.9 m high. What is the rotational
kinetic energy of the hoop after it has rolled without slipping to
the bottom?
