Question

The shaft of a motor rotates at a constant angular velocity

Answer 1

Answer:

3000 revolutions / min = ( 3000×2π ) radians/( 60 s) = 100π radians / second

Explanation:

Given, ω=3000rpm

ω=3000rpm

For rotation per second, we have

ω=300060rps= 50rps ×2πrad/s

   =100πrad/s=100πrad/s

∴θ=ωt=100πrad
