What is its angular speed after it has turned through an angle of 15 radians? A grindstone, initially at rest, is given a constant angular acceleration so that it makes 5 rev in the first 10 s. What is its angular acceleration? A string is wrapped around a pulley of radius 1 m and moment of inertia 5 kg m2. If the string is pulled with a force . F, the resulting angular acceleration of the ...

Thinking about a car starting up, you decide to calculate how the angular speed of a spinning object changes when it is brought into contact with another object at rest. To keep your calculation simple, you decide to use a disk for the initially spinning object and a ring for the object initially at rest. Both objects will be able to rotate freely about the same axis that is centered on both ...
Sample test 3
The angular speed of each blade is the same; however, each blade rotates in the opposite direction. Therefore, it is correct to conclude that the blades have opposite angular velocities at any instant during the cut. _____ 3. REASONING AND SOLUTION . Just before the clock is unplugged, the second hand is rotating so that its angular velocity is clockwise. The second hand moves with a constant ...
