A Brunswick bowling ball with mass M= 7kg and radius R=0.15m
rolls from rest down a ramp without slipping. The initial height of
the incline is H= 2m. The moment of inertia of the ball is
I=(2/5)MR2
What is the total kinetic energy of the bowling ball at the
bottom of the incline?
684J
342J
235J
137J
If the speed of the bowling ball at the bottom of the incline is
V=5m/s, what is the rotational speed ω at the...

1. A cylindrical wooden log rolls without slipping down a small
ramp. The log has a radius of 16 cm, a length of 2.5 m, and a mass
of 130 kg. The log starts from rest near the top of the ramp. When
the log reaches the bottom of the ramp, it is rolling at a linear
speed of 2.3 m/s.
a.) Assuming that the log is a perfect cylinder of uniform
density, find the log’s moment of inertia (about...

A solid cylinder of mass 1.3 kg and radius 2.0 cm starts from
rest at some height above the ground and rolls down an ncline
without slipping. At the bottom of the incline, its linear speed is
2.5 m/s. (a) How much is its angular speed? (b) How much is its
rotational kinetic energy? The moment of inertia of a solid
cyllinder is 21mR2 (c) How much is its total energy at the bottom?
(d) From what height did it...

1) A ball of 2 kg rolls without slipping along a horizontal
floor with a velocity of 10m/s.
1a) find the rotational kinetic energy of this ball.
1b) Now, the ball rolls up an inclined ramp (rolls without
slipping). What height does the ball reach along the ramp before it
finally stops?
2) Consider a stick of total mass M and length L rotates about
one end. Since the stick gets heavier as you move along a stick,
the stick...

A solid metal ball starts from rest and rolls without slipping a
distance of d = 4.2 m down a θ = 38° ramp. The ball has uniform
density, a mass M = 4.7 kg and a radius R = 0.33 m.
What is the magnitude of the frictional force on the sphere?

A ball of mass M and radius R rolls smoothly from rest down a
ramp and onto a circular loop of radius 0.47 m. The initial height
of the ball is h = 0.35 m. At the loop bottom, the magnitude of the
normal force on the ball is 2.0 Mg. The ball consists of an outer
spherical shell (of a certain uniform density) that is glued to a
central sphere (of a different uniform density). The rotational
inertia of...

A solid cylinder starts rolling without slipping from the top of
an inclined plane. The cylinder starts moving from rest at a
vertical height 10m. The mass of the cylinder is 1kg and its radius
is .5m. The moment of inertia of the cylinder is 1/2 mr2
(where m is the mass of the cylinder and r is its radius).
C.What is the rotational kinetic energy of the cylinder when its
vertical height is 3 m?
D.What is the translational...

A ball rolls without slipping down a ramp with a 20 degree
slope. If the ball starts 2.0m higher than the end of the ramp and
the ramp is 3.0m above the ground, how far out from the end of the
ramp does the ball land? I(ball)= 2/5 mr^2

A solid cylinder starts rolling without slipping from
the top of an inclined plane. The cylinder starts moving from rest
at a vertical height 10m. The mass of the cylinder is 1kg and its
radius is .5m. The moment of inertia of the cylinder is 1/2
mr2 (where m is the mass of the cylinder and r is its
radius).
What is the speed of the center of mass of the
cylinder when its vertical height is 4 mm ?...
