Compare the terms and units for both this
and the original (i.e., translational and rotational) versions of Newton's
2nd law.

A potter's wheel has a radius of 0.50 m and a mass of 100.0 kg and is freely rotating at 50.0 rev/min. The potter can stop the wheel in 6.0 s by pressing a wet rag against the rim.

-a) What is the angular acceleration of
the wheel?

-b) How much torque does the potter apply
to the wheel?

What is angular momentum?

What is the formula for angular momentum?

Compare the terms and units for both this
and the original (i.e., translational and rotational) versions of the formula
for angular momentum.

A 2.0 kg bicycle wheel with a radius of
0.30 m turns at a constant angular speed of 25 rad/s when a 0.30 kg reflector
is at a distance of 0.19 m from the axle. What is the angular speed
of the wheel when the reflector slides to a distance of 0.25 m from the
axle?

What is rotational kinetic energy?

What is the basic formula for kinetic energy?

What is the formula for rotational kinetic
energy?

Write the updated version of the formulas
for the conservation of mechanical energy.

A 1.5 kg bicycle tire with a radius of
0.33 m starts from rest and rolls down from the top of a 14.8 m high hill.
What is the translational speed of the tire when it reaches the bottom
of the hill? (Assume the tire is a hoop with a I = mr2.)
