A body is whirled in a horizontal circle of radius 25 cm . It has an angular velocity of 13rad/s13 \mathrm{rad} / \mathrm{s}. What is its linear velocity at any point on circular path?

Options

  1. A2 m/s2 \mathrm{~m} / \mathrm{s}
  2. B3 m/s3 \mathrm{~m} / \mathrm{s}
  3. C3.25 m/s3.25 \mathrm{~m} / \mathrm{s}
  4. D4.25 m/s4.25 \mathrm{~m} / \mathrm{s}

Correct answer

C. 3.25 m/s3.25 \mathrm{~m} / \mathrm{s}

Step-by-step solution

Given, r=25cm=0.25mω=13rad/s\begin{aligned} r & =25 \mathrm{ cm}=0.25 \mathrm{ m} \\ \omega & =13 \mathrm{rad} / \mathrm{s}\end{aligned}\becauseLinearspeed=RadiusLinear speed = Radius\timesAngularspeedAngular speed or v=rω∴=0.25×13⇒v=3.25m/s\begin{array}{llrl}\text{ or } & & v & =r \omega \\ \therefore & & & =0.25 \times 13 \\ \Rightarrow & & v & =3.25 \mathrm{ m} / \mathrm{s}\end{array}$
