3. A sphere of mass m and radius r is released from rest at the top of a curved track of height H. The sphere travels down the curved track and around a loop of radius R. The sphere rolls without slipping during the entire motion. Point A on the loop is at height R, and point B is at the top of the loop. The rotational inertia of the sphere is 2mr2/s. Express all of...

A disk of m=5 kg and radius r=2 m starts from rest and rolls down a 20 degree incline from an initial height of 50 m. What is the linear velocity of the disk as it reaches the bottom of the incline? What is the rotational kinetic energy of the disk at the halfway point between the positions 1 and 2? If it takes 1.2 seconds for the disk to reach the bottom of the incline, find the magnitude of...

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...
