A .13 kg disk is rotating at an angular speed of 57 rad/s. The disk has a radius of .25m. The disk speeds up for 3 s. After the 3 s have passed, the edge of the disk is under a centripetal forxe of 313.13 N. What is the centripetal acceleration of the disk at this time?
What is the final angular velocity of the disk after the 3 s?
What is the angular acceleration during the 3 s interval (assume constant)?
How many revolutions does the disk make during the time it is accelerating?

A disk (mass of 3 kg, radius 30 cm) is rotating with an angular velocity w1= 5 rad/s. A second disk (mass 2kg, radius 15cm), which is rotating at w= -7 rad/s is dropped on top of the first disk. The disks are dropped so that they share a rotational axis, and they stick together. The moment of inertia of a disk is 1/2mr^2. What is the final angular speed of the two disks?

A solid disk is rotating about a frictionless axle with an initial angular velocity of 15 rad/s in a clockwise direction. The disk has a mass of 5.0 kg and a radius of 15 cm. A force of 20 N is applied to the disk for 0.5 s. This force is applied in a direction tangent to the edge of the disk that causes the disk to increase speed in the clockwise direction. I (disk) = ½ MR^2 a. What...

A 3 kg disk of radius 0.25 m is rotating freely at an angular speed of 100 rad/s on a shaft passing through the center if mass of the disk. A 2 kg solid ball of the same radius, initially not rotating, slides down the shaft (the shaft passes through the ball's center of mass) and is coupled to the disk. Assuming that the rotational inertia is of the shaft is negligible, a) what is the angular speed of the...

A floor polisher has a rotating disk that has a 13-cm radius. The disk rotates at a constant angular velocity of 1.7 rev/s and is covered with a soft material that does the polishing. An operator holds the polisher in one place for 34 s, in order to buff an especially scuffed area of the floor. How far does a spot on the outer edge of the disk move during this time
