Answer:
the final angular velocity of the particle is approximately 38.18 Rad/s
Explanation:
To start with, let's make sure that units of angle measure are the same, converting everything into radians:
And now we can use the kinematic formulas for rotational motion:
Therefore we can find the initial angular velocity of the particle:
and now we can estimate the final angular velocity using the kinematic equation for angular velocity;
Systems always tend toward a state of decreasing order unless more energy is provided into the system to counteract this tendency.
