To answer this item, we use dimensional analysis and conversion factor, 1 revolution is equal to 2π rad. Using the concept and the given,
n = (14.2 revolutions / 8 seconds)(2π rad/1 rev)
n = 11.15 rad/s
Thus, the angular velocity is equal to 11.15 rad/s.
0.377 + 5.51 = 5.887
Sorry I can only solve the first one. Could you give me a hint on how to do the second one ?
You can answer some questions that say (PLEASE ANSWER I WILL GIVE YOU BRAINIEST!!!!!!!) it usually happens if you answer it first ;D
