Apoint on the edge of a flywheel with a radius of 16 cm is rotating at a rate of 10 radians per second. what is the linear speed of a point on its rim, in centimeters per minute?

9600 cm/min

Explanation:

Well, the circumference of the flywheel is 2π×the radius(16 cm). That's how far the spot moves in one revolution.

10 radians per second divided by 2π is the number of revolutions per second.

So multiply that times the circumference and that's the distance the point has traveled.

let the linear speed of the spot be v

therefore, v= 160×60= 9600 cm/min

i'd say that the moon rock is about 2.2 billion years old.

true, i don't really know what you're asking but from the info you provided im guessing the answer is true.
