bowling ball (solid sphere) with r = 1.5m and m = 6.3kg rotates about its axis due to a angential force of F = 45N. what is the angular acceleration (in rad/s2) of the sphere?

A small fan has blades that have a radius of 0.0600 m. When the fan is turned on, the tips of the blades have a tangential acceleration of 23.5 m/s2 as the fan comes up to speed. What is the angular acceleration α of the blades?

The wheels of a sport car go from rest to 3000 rpm in 3 second. Its angular acceleration a is rad/s?. Type your answer.

An optical disk drive in a computer can spin a disk at up to 10,000 rpm. If a particular disk is spun at 2250 rpm while it is being read, and then is allowed to come to rest over 0.301 s, what is the magnitude of the average angular acceleration of the disk? angular acceleration: 782.79 rad/s? If the disk is 12.0 cm in diameter, what is the magnitude of the tangential linear acceleration of a point 1/11 of the way out from the center of the disk? linear acceleration: m/s?

A cylinder 37 cm in diameter is at rest initially. It is then given an angular acceleration of 0.183 rad/s^2. Find the angular velocity at 7.86 s. Give your answer in rad.

A platform is rotating with an angular speed of 3.00 rad/s and an angular acceleration of 11.0 rad/s². At a point on the platform that is 1.26 m from the axis of rotation, what is the magnitude of the total acceleration a?

A dentist's drill starts from rest. After 4.30 s of constant angular acceleration it turns at a rate of 2.05 ✕ 104 rev/min. (a) Find the drill's angular acceleration. rad/s2(b) Determine the angle (in radians) through which the drill rotates during this period.
