Alright Dude, If that worked for you... dont forget to give THUMBS UP.(that will work for me!)
If I missed something feel free to leave a comment.
atleast before giving downvote.
and, Thanks for using homeworklib- Smarter way to study.

A hollow sphere and uniform sphere of the same mass m and radius R roll down an inclined plane from the same height H without slipping (Figure 9-59). Each is moving horizontally as it leaves the ramp. When the spheres | hit the ground, the range of the hollow sphere is L. Find the range L' of the uniform sphere. FIGURE Uniform Hollow sphere sphere

Two spheres of equal mass M and equal radius R roll down an
inclined plane as shown in the figure. One sphere is solid and the
other is a hollow spherical shell. The plane makes an angle ? with
respect to the horizontal. The spheres are released simultaneously
from rest at the top of the inclined plane and they each roll down
the incline without slipping.
The total distance each sphere rolls down the ramp (the
hypotenuse) is d. There...
Two uniform spheres of identical mass and radius are placed on inclined planes at the same...
Two uniform spheres of identical mass and radius are placed on
inclined planes at the same height h and inclination angle θ. One
plane is rough and causes one sphere to roll down the plane; the
other is frictionless, and so the sphere on it slides down the
incline.
Find the ratio of the kinetic energies of the two spheres at the
bottom of the incline: .

Two wheels having the same radius and mass rotate at the same angular velocity. One wheel is made with spokes so nearly all the mass is at the rim, as shown. The other is a solid disk. How do their rotational kinetic energies compare?

Please answer this two part question
A solid sphere of mass m and radius a rolls without slipping down a ramp that has a height h and is inclined at angle 0. The sphere is initially motionless. It takes 10 s for the sphere to roll to the bottom of the ramp. 2. a) Would a hoop of the same mass and radius take the same time, or more, or less? Explain. MR The hoop has a maller coeficient from...
A hollow sphere of mass m = 0.35 kg and radius r = 64 cm rolls...
A hollow sphere of mass m = 0.35 kg and radius r = 64 cm rolls along a flat surface at an initial speed of v, and then up a curved ramp with radius of curvature 4.7 m without slipping, until it reaches a maximum angle of 12 degrees around the curve and starts to roll backward. What was the initial speed of the ball in units of meters/second?

3. Two solid cylinders with different radii (r and 2r) and lengths (21 and 1) and the same mass spin on an axle at the same angular speed (wo) in opposite directions (assume they are spinning on frictionless bearings). Christian slowly brings the two cylinders together (without affecting their rotation). The friction between the flat surfaces results in the cylinders having the same angular velocity. a. Determine the magnitude of the final angular velocity in terms of wo. b. By...
A solid uniform sphere and a uniform spherical shell, both having the same mass (m) and...
A solid uniform sphere and a uniform spherical shell, both having the same mass (m) and radius (R), rolls without slipping along a horizontal surface at a speed v. They then encounter a hill that rises at an angle (theta) above the horizontal. (I of the sphere = 2/5mR^2) and (I of the spherical shell = 2/3mR^2) (a) How high will the sphere roll before coming to rest? (b) How high will the spherical shell roll before coming to rest?...

Rolling and Torque Two spheres of the same mass are positioned on a 100 meter ramp with at 20 degree incline. Both spheres have a radius or 5 m and mass of 1000 kg (HUGE SPHERES, think Indiana Jones). The difference is how the mass is distributed. One sphere is completely solid with mass equally distributed throughout it. The second mass has all of its mass distributed at the edge of its radius in a thin shell. So, one...
