1. When a point on the edge of a DVD (radius 6.0 cm) moves along an arc of length 120 cm, through what multiple of π rad does the disk turn? 2. With an angular velocity of 3.4π rad/s, how much time is required to complete 11 complete revolutions? 3. The blades of a kitchen blender rotate counterclockwise at 2.2x10^4 rpm (revolutions per minute) a top speed. It takes the blender 2.1 seconds to reach this top speed after being...

An electric ceiling fan is rotating about a fixed axis with an initial angular velocity magnitude of 0.200 rev/s . The magnitude of the angular acceleration is 0.886 rev . Both the angular velocity and angular acceleration are directed clockwise. The electric ceiling fan blades form a circle of diameter 0.770m. A). Compute the fan's angular velocity magnitude after time 0.198 s has passed. B). Through how many revolutions has the blade turned in the time interval 0.198 s from...

Problem #1 m1 m2 Two blocks mı = 4 kg and m2 = 9 kg are initially arranged as shown in the figure. They are tied to a massless rope going around the pulley. The pulley has a form of a cylinder with a mass of M = 8 kg and radius of R = 40 cm. Both the incline and the horizontal surface have a coefficient of kinetic friction ulk = 0.15. The incline is at the angle o...

1. Three children are riding on the edge of a merry‑go‑round that has a mass of 105 kg and a radius of 1.80 m. The merry‑go‑round is spinning at 22.0 rpm. The children have masses of 22.0, 28.0, and 33.0 kg. If the 28.0 kg child moves to the center of the merry‑go‑round, what is the new angular velocity in revolutions per minute? Ignore friction, and assume that the merry‑go‑round can be treated as a solid disk and the children...
