Question

a machine wheel spins at a rate of 500 revolutions per minute. if the wheel had a diameter of 80 centimeters, what is the angular speed of the wheel, in radians per second? round your answer to the nearest hundredth. ______ rad/sec

Answer 1

Answer:

Angular speed, =  52.35 radians per second

Step-by-step explanation:

It is given that,

A machine wheel spins at a rate of 500 revolutions per minute

Diameter of wheel, d = 80 cm

We have to find the angular speed of the wheel in radian per second.

Revolution/minute can be converted to radian/minute by by multiplying 2π.

500 revolutions/minute = 500 × 2π radian/minute = 1000π radian/minute

Since, 1 minute = 60 seconds

500 revolutions/minute = 1000π/60 = 52.35 radians per second

Hence, this is the required solution.

Answer 2

I think it is 40000 and what is rad
