Question

Fiat panda is rotating with an angular velocity omega without any axis through its centre

Answer 1

ue

OO)

Bre]

rotating about an axis XY with uniform angular

velocity W.

Let rq, 1g

Jn be the distances of particles

from the axis of rotation.

Different particles are at different distances from

the axis of rotation, therefore, the magnitude of

linear velocities of different particles will be

different.

i

Consider it" particle of mass mj at a distance

1; from the axis of rotation.

The linear speed of it" particle will be

Vi=T

Therefore, kinetic energy of ith particle due to

rotation about XY-axis is,
