Question

An object of mass 4kg moves round a circle of radius 6m with constant speed 12ms calculate,the angular speed and the force toward the center

Answer 1

Explanation:

what is centripatal force

Answer 2

The angular speed is 2 rad/s and the centripetal force is 96 N.

Given,

Mass of the object = 4 kg.

The radius of the circle = 6 m.

To Find,

The angular speed and the force towards the center.

Solution,

The formula for calculating the angular speed of an object is

ω = V/R

where V is the velocity and R is the radius

ω = 12/6 = 2 rad/sec

Now, the formula for calculating the centripetal force is

Force = mv²/R

Force = 4(12)²/6

Force = 96 N.

Hence, the angular speed is 2 rad/s and the centripetal force is 96 N.
