The angular displacement of body performing circular motion is given by =5 t 6 . The angular velocity of the body at t=3 second will be [ 2 =1, 2 =0 ]

Options

  1. A5 rad s
  2. B1 rad s
  3. C2.5 rad s
  4. Dzero

Correct answer

D. zero

Step-by-step solution

aligned & =5 t 6 & d dt = 6 5 t 6 & At t =3 ~s , d dt = 5 6 3 6 = 5 6 2 =0 aligned
