Angular Kinematics
The wheels of a bicycle spin with an angular speed of The cyclist applies the brakes causing uniform deceleration, and after of deceleration, the wheels are spinning at From the moment the brakes are applied, how long will it take for the bicycle to come to a complete stop?
A tire with radius moves forward with a linear speed of What is its angular speed?
The moment of inertia of a turbine in a jet engine is It is accelerated uniformly from rest to an angular speed of in seconds. Find the magnitude of net torque required.
At the local swimming hole, a favorite trick is to run horizontally off a cliff that is above the water, roll yourself up into a "ball", and rotate on the way down to the water. If the average angular speed of rotation is revolutions per second, what is the total number of revolutions during the fall?
The air resistance is negligible, and the gravitational acceleration is
A figure skater is spinning with an angular velocity of She then comes to a stop with a constant deceleration over a brief period of time. During this time, her angular displacement is Determine the approximate magnitude of her angular acceleration.
