A motor provides the torque necessary to keep a gear turning at
constant angular velocity, overcoming friction between the gear and
the axle.
The gear can be modeled as a disk, with mass 2 kg, and radius
rg = 0.2 m. The force of friction can be
modeled as a single force, acting at the outer edge of the axle, at
position ra = 0.02 meters, with force of
fk = 10 N.
a) What is the magnitude of the...

Part : Problem Solving (12 points each) Instructions: Solve all four problems. 1. The Schwerer Gustav was a huge railway gun used in wW II. The railway gun had an unloaded mass of 1.35 x 10° kg and fired shells with a mass of 7000 kg. If both the gun and the shell were stationary to start and the shell is fired at 820 m/s, what is the recoil velocity of the gun? 2. A 850 kg car initially going...

INVESTIGATION 10 ROTATIONAL MOTION OBJECTIVE To determine the moment of inertia I of a heavy composite disk by plotting measured values of torque versus angular acceleration. THEORY Newton's second law states that for translational motion (motion in a straight line) an unbalanced force on an object results in an acceleration which is proportional to the mass of the object. This means that the heavier...

10*) The Sun has approximate radius 7×108 m, and rotates around
its axis once every 27 days. a) Find its angular velocity in rad/s,
and (assuming it is a uniform sphere) write a formula for its
angular momentum expressing it in terms of its mass M (you do not
need to substitute a value for M). b) Suppose the Sun were to
collapse to a neutron star, which is a much denser state, without
losing any mass and without being...

1. Three children are riding on the edge of a merry‑go‑round that has a mass of 105 kg and a radius of 1.80 m. The merry‑go‑round is spinning at 22.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry‑go‑round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry‑go‑round can be treated as a solid disk and the children...
