Re: Need help urgently would really appreciate any help regarding Angular Velocity im confused because i don't have the arc length so i won't be able to work out the angle? the formula for the arc length is angle x pi x r / 180 and to work out the area its s x r / 2

(i) A rotating machine shaft turns through 2100 revolutions in 3 minutes. Determine the average angular velocity, w, of the machine shaft in rad/s. the answer for this is 2100 x 2 pie = 4200 pie radian 3 mins = 180 seconds 4200 / 180 = 73.3 rad/s (ii) Determine the area and arc length of the...
