Question

A body is whirled in a horizontal circle of radius 20 cm. it has an angular velocity of 10 rad . what is its linear velocity at any point on circular path

Answer 1

"Here is the answer:

To find linear velocity= v=?

Given :- A body is whirled in a horizontal circle of radius= r=20cm = 0.2m

The body has an angular velocity of w= 10 rad/s

Using and putting the given values in the formula v= r w

We get,

v = 0.2 × 10

v = 2m/s.

Therefore answer, 2m/s is linear velocity of the body at any point on circular path. "

Answer 2

Answer:2m/s

Explanation:w(angular velocity) =10 rad/s

r( radius) = 20 cm =0.2m

w=v/r ( v= linear velocity)

10=v/0.2

V=10×0.2

=2m/s
