Answer #1

An 6.90-cm-diameter, 360 g solid sphere is released from rest at
the top of a 1.80-m-long, 20.0 ∘ incline. It rolls, without
slipping, to the bottom. What is the sphere's angular velocity at
the bottom of the incline? What fraction of its kinetic energy is
rotational?

An 8.20 cm-diameter, 390g solid sphere is released from rest at
the top of a 2.00m long, 19.0 degree incline. It rolls, without
slipping, to the bottom.
1) What is the sphere's angular velocity at the bottom of the
incline?
2) What fraction of its kinetic energy is rotational?

A solid sphere of ice and a solid sphere of plastic are placed
at the top of an inclined plane of length L and simultaneously
released from rest, as shown in (Figure 1). Each has mass m and
radius R. Assume that the coefficient of friction between the ice
sphere and the incline is zero and that the plastic sphere rolls
down the incline without slipping. Derive expressions for the
following quantities in terms of L, θ, m, and R:...

the incline?
b. From what height must a solid disk with the same mass and
radius be released from rest to have the same velocity at the
bottom? It also rolls without slipping.
