- A rotating flywheel rotates at 400 revolutions in the first minute. In the next minute, it rotates 240 revolutions. If the number of revolutions decreases as a constant rate, how many revolutions will the wheel make before coming to a rest?A wheel of radius 75cm is rotating with a frequency of 3.0Hz about a fixed axis of rotation. What is the speed of a piece of chewing gum stuck to the rim?A centrifuge in a medical laboratory rotates at an angular speed of 3,550 rev/min. When switched off, it rotates through 54.0 revolutions before coming to rest. Find the constant angular acceleration (in rad/s2) of the centrifuge.
- A rock tied to the end of the string swings at a constant angular rate. If you are told that the string can support a total of 100 N of force before breaking, what is the maximum angular velocity the rock can rotate if the rock has a mass of 0.2 kg, and the length of the string is 0.5m? Give your answer in units of radians per second.You have a horizontal grindstone (a disk) that is 87 kg, has a 0.31 m radius, is turning at 94 rpm (in the positive direction), and you press a steel axe against the edge with a force of 23 N in the radial direction. The kinetic coefficient of friction between steel and stone is 0.20. What is the number of turns, N, that the stone will make before coming to rest?A washing machine needs 17.1 s to speed up from rest to top speed of 5 rotation for every 3.05 s. If the damp cloths inside are 9.87 cm from the center, what is it's radial acceleration at top speed?
- You are on a Ferris Wheel that spins at 2.8 rpm. The ride is 29.8 m across. What is your apparent weight at the top of the ride if you have a mass of 87.6 kg?A flywheel slows from 570 to 422 rev/min while rotating through 170 revolutions. What is the angular acceleration of the body?A windmill wheel makes 4.5 revolutions a second.
