A solid flat disk is rotating in the counter-clockwise (or positive) direction. There is an object (small black dot) on the disk, rotating with the disk. The object is a distance 1.20 meters from the axis of rotation (the center of the disk). It had an angular velocity of 3.50 radians / second at the initial position of 0 Radians (see black line on image). After 1.53 seconds, it has an angular velocity of 7.50 radians / second at the position shown in the picture.

At t= 0 a grinding wheel has an angular velocity of 30.0 rad/s. It has a constant angular acceleration of 35.0 rad/s² until a circuit breaker trips at time t = 1.70 s. From then on, it turns through an angle 438 rad as it coasts to a stop at constant angular acceleration. Through what total angle did the wheel turn between t= 0 and the time it stopped?

You are in a tall building located near the equator. As you ride an elevator from the ground floor to the top floor, your tangential speed due to the earth's rotation O increases O decreases O increases when the speed of the elevator increases and decreases when the speed of the elevator decreases does not change

A cylindrical shaped object of mass 5.0 kg and radius 0.25 m is rotating at 11 rad/s. An object is dropped so that it sticks to the cylinder at a distance of 0.10 m from the axis of rotation, and the system’s angular speed decreases to 10.5 rad/s. What is the mass of the dropped object?

A pitcher throws a curveball that reaches the catcher in 0.64 s. The ball curves because it is spinning at an average angular velocity of 380 rev/min (assumed constant) on its way to the catcher's mitt. What is the angular displacement of the baseball (in radians) as it travels from the pitcher to the catcher?

A pulsar is a rapidly rotating neutron star that continuously emits a beam of radio waves in a searchlight manner. Each time the pulsar makes one revolution, the rotating beam sweeps across the earth, and the earth receives a pulse of radio waves. For one particular pulsar, the time between two successive pulses is 0.027 s. Determine the average angular speed (in rad/s) of this pulsar. rad/s

A motorcyclist is traveling along a road and accelerates for 6.94 s to pass another cyclist. The angular acceleration of each wheel is +8.39 rad/s2, and, just after passing, the angular velocity of each is +80.6 rad/s, where the plus signs indicate counterclockwise directions. What is the angular displacement of each wheel during this time?

A figure skater is spinning with an angular velocity of +13.1 rad/s. She then comes to a stop over a brief period of time. During this time, her angular displacement is +3.84 rad. Determine (a) her average angular acceleration and (b) the time during which she comes to rest.

A figure skater is spinning with an angular velocity of +16.4 rad/s. She then comes to a stop over a brief period of time. During this time, her angular displacement is +3.65 rad. Determine (a) her average angular acceleration and (b) the time during which she comes to rest.

A Lazy Susan (turning tabletop) has radius 0.75. An apple is placed at the edge of the turning table. A child turns the tabletop from rest to an angular speed of 5.00 rev/min in 3.00 s. What is the value of the angular speed in rad/s? Your Answer: Answer Question 24 (4 points) A Lazy Susan (turning tabletop) has radius 0.750 m. An apple is placed at the edge of the turning table. A child turns the tabletop from rest to an angular speed of 5.00 rev/min in 3.00 s.
