Question

- A particle moves in a circle of radius 5m with an
angular speed 4 rads 1 it's linear speed​

Answer 1

Here we use the equation,

v = rx

where, v is the linear speed

r is the radius

x is the angular speed

Given that,

r = 5m

x = 4 rad/s

Therefore,

v = rx

= 5×4 = 20m/s

Therefore the linear speed is 20m/s

Answer 2

Answer:

A particle moves in a circle of radius 5m with an  angular speed 4 rad/sec its linear speed​ is 20m/s

Explanation:

• In a circular motion, the linear velocity (V) and angular velocity (w) are related as,

        $V=rw$

        where r-radius of the circular path

From the question, it is given that

the radius of the circular path $r=5m$

the angular velocity of the particle,$w=4rad/sec$

substitute the given values, we get

the linear velocity of the particle $V=5*4=20m/s$
