Question

an angular speed of an object making 120 revolutions per minute.calculate the angular speed.

Answer 1

Answer:

I will tell you the method to convert revolutions per minute (rpm) to

radian/sec.

You need to multiple with 2π/60

Dividing with 60 because we are converting from minutes to seconds.

Again Multiplying by 2π because we are converting from revolutions to angle( unit: radian).
