determine the angular velocity if 0.75 revolutions are completed in .05 seconds a) 9.4 radians/sec b) 47.1 radians/ sec c)94 radians/sec d) 4.7 radians/sec
If you have 0.75 revs/0.05 secs, you can multiply top and bottom by 20 to get 15 revs/sec. Each rev is 2(pi) radians, so you have 15 x 2 x pi radians/sec = 30pi rads / sec = approx. 94 rads/sec.
