A truck with 0.420 m radius tires travels at 32.0 m/s. What is the angular velocity of the rotating tires in radians per second? What is this in rev/min? Assume a cell membrane is about 10–8 m thick.

A flywheel slows from 517.7 rev/min down to 364.9 rev/min while spinning through 44.4 revolutions. What is the angular acceleration of the flywheel (in rad/s/s)? Assume that the flywheel slows down at a constant rate.

A bicycle wheel is rotating at 40 rpm when the cyclist begins to pedal harder, giving the wheel a constant angular acceleration of 0.50 rad/s^2 What is the wheel's angular velocity, in rpm, 8.0 s later?

June started winding up her arm holding a baseball, moving it around her shoulder in a circle, to get ready to throw. June’s arm is 0.5 m long and moves at an angular velocity of 2 rad/s. How much time will 10 revolutions take? What is the velocity of the baseball when she let go of it?

A child sits on a merry-go-round that has a diameter of 4.00 m. The child uses her legs to push the merry-go-round, making it go from rest to an angular speed of 17.0 rpm in a time of 43.0 s. What is the average angular acceleration aavg of the merry-go-round in units of radians per second squared (rad/s?)? davg = rad/s2 What is the angular displacement Að of the merry-go-round, in units of radians (rad), during the time the child pushes the merry-go-round?

A fan blade with a diameter of 1.373 m is rotating at a rate of 3898 revolutions per minute. A piece of gum that is attached to the end of the fan blade suddenly becomes loose while its velocity vecor was momentarily pointing straight up. How long will it take for the piece of gum to come back down? Assume that there is no air resistance.

The tires of a car make 85.0. revolutions as the car reduces its speed uniformly from 90.0 km/hr to 60.0 km/hr. The tires have a diameter of 0.90 m. What is the angular acceleration? If the car continues to slow down at this rate, how much more time is required to stop?

A 20 cm diameter circular saw blade spins at 3900 rpm. How fast would you have to push a straight hand saw to have the teeth move through the wood at the same rate as the circular saw teeth?

An automobile with 0.300 m radius tires travels 70,000 km before wearing them out. How many revolutions do the tires make, neglecting any backing up and any change in radius due to wear? x revolutions A truck with O.600 m radius tires travels at 29.0 m/s. At how many radians per second are the tires rotating? What is this in rpm? гad/s rpm
