A spinning top is an old child's toy that spins on a pointed end. A top is spinning at 4 rev/s and comes to a stop in 64 seconds. Assume the top slows down with constant angular acceleration. An insect is unfortunate enough to be sitting on the edge of the 3 cm radius spinning top.

a. What is the tangential acceleration of the insect?

b. How many revolutions does it make before coming to a stop?

c. How many meters has the insect traveled during these revolutions?

1. A disk of mass M=160kg and radius R=0.40m spins with an initial rate of 12 revolutions per second. Because of friction in the bearing, the disk slows down at a uniform rate. After 20 minutes it comes to a stop. (a) How many revolutions does the disk make before coming to rest? (b) What is the moment of inertia of the disk? (c) Find the angular acceleration of the disk as it slows down. (d) Find the torque that...

A top is a toy that is made to spin on its pointed end by pulling on a string wrapped around the body of the top. The string has a length of 66 cm and is wound around the top at a spot where its radius is 1.4 cm. The thickness of the string is negligible. The top is initially at rest. Someone pulls the free end of the string, thereby unwinding it and giving the top an angular acceleration...

A flywheel in a motor is spinning at 550 rpm when a power failure suddenly occurs. The flywheel has mass 40.0 kg and diameter 75.0 cm . The power is off for 40.0 s , and during this time the flywheel slows down uniformly due to friction in its axle bearings. During the time the power is off, the flywheel makes 210 complete revolutions. A) At what rate is the flywheel spinning when the power comes back on? Answer in...
