Wired Faculty App

A body is whirled in a horizontal circle of radius 25 cm. It has an angular velocity of 13 rad/s. What is its linear velocity at any point on circular path?

  • 2 m/s

  • 3 m/s

  • 3.25 m/s

  • 4.25 m/s

Answer

C.

3.25 m/s

Given:- r = 25 cm =  m

  ω = 13 rad/s

   Linear speed  = Radius × angular speed

            V = rω

          = 0.25 × 13

        3.25 m/s
