Calculate the tangential speed of an object traveling along a circular path at an angular velocity of 55 degrees/second at a radius of 2.5 cm.

A diver runs horizontally off the end of a diving tower 3.5m above the surface of the water with an initial speed of 2.5 m/s. During her fall she rotates with an average angular speed of 2.6 rad/s How many revolutions has she made when she hits the water? Express your answer using two significant figures.Δθ= (?) rev

An auto with 0.300 m radius tires travels 65,000 km before wearing them out. How many revolutions do the tires make, neglecting any backing up and any change in radius due to wear? What is the basic relationship between angular and linear displacement?

A floppy disk rotates with a constant angular speed of 56.4 rad/s.Find the tangential speed at a point 0.073 m from the axis of rotation.What is the magnitude of the centripetal acceleration at this point?

If a centrifuge pushes the astronauts to 5g's with a radius of 10m, (i) what is the angular velocity of the centrifuge? (ii) what is the tangential velocity? (iii) what would be the angular velocity if the centrifuge worked at 9g's? (iv) in a uniform circular motion, which stays constant, the magnitude of the velocity vector or the direction of the velocity vector
