(6) A car wheel 30 cm in radius is turning at a rate of 8.0 rev/s when the car begins to slow uniformly to rest in time of 14 s. Find the number of revolutions made by the wheel and the distance the car goes in t 14 s.

A disc accelerates uniformly from 300 revolutions per minute to 600 revolutions per minute in 25 (s). What is the linear acceleration of a point on the rim of the disc, if the radius of the disc is 250 mm.

How fast (in rpm) must a centrifuge rotate if a particle 7.5 cm from the axis of rotation is to experience an acceleration of 2.0×105 g's? Express your answer using two significant figures.

Suppose a piece of dust finds itself on a CD. If the spin rate of the CD is 380 rpm, and the piece of dust is 4.0 cm from the center, what is the total distance (in m) traveled by the dust in 9 minutes? (Ignore accelerations due to getting the CD rotating.)

A bug on a bicycle wheel moves in a circle through 40 pie radians. If the radius of the wheel is 0.6 meters in length, what is the total linear distance the rock moved?

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?

An object with mass 125 g is in a circular motion. If the mangitude of the centripetal force is 18N amd the angular velocity is 23.2 rad/s, what is the radius of the circular path in  the unit of meters?

How fast (in rpm) must a centrifuge rotate if a particle 9.50 cm from the axis of rotation is to experience an acceleration of 117000 g's? If the answer has 4 digits or more, enter it without commas, e.g. 13500.
