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.
(a) Find the ratio of the kinetic energies of the two spheres at
the bottom of the incline: .
(b) Find the ratio of their speeds at the base of the...

Two uniform solid spheres have the same mass, 1.65 kg, but one has a radius of 0.256 m while the other has a radius of 0.844 m. For each of the spheres, find the torque required to bring the sphere from rest to an angular velocity of 357 rad/s in 10.5 s. Each sphere rotates about an axis through its center. a)Torque on sphere with the smaller radius. b)Torque on sphere with the larger radius. c)For each sphere, what force...

Two spheres with uniform surface charge density, first with a radius of 7.2 cm and the second with a radius of 4.8 cm , are separated by a center-to-center distance of 33 cm. The spheres have a combined charge of +55μC and repel one another with a force of 0.65 N . Assume that the charge of the first sphere is greater than the charge of the second sphere. PART A) What is the surface charge density on the first...

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...
