A person exerts a tangential force of 37.2 N on the rim of a disk-shaped merry-go-round of radius 2.70 m and mass 158 kg. If the merry-go-round starts at rest, what is its angular speed after the person has rotated it through an angle of 32.5°?
The head of a grass string trimmer has 100 g of cord wound in a light cylindrical spool with inside diameter 3.00 cm, What average power is delivered to the head by the trimmer motor while it is accelerating
You are an astronaut (m = 115 kg) and travel to a planet that is the same mass and size as Earth. This new planet, however, rotates more rapidly with a period of only 4 h. Considering the centripetal acceleration caused by this rotation, what is the ..
