Determine the kinetic energy of a circular disc rotating with a speed of 60 rpm about an axis passing through a point on its circumference and perpendicular to its plane. The circular disc has a mass of 5 kg and radius 1 m.

Determine the kinetic energy of a circular disc rotating with a speed

1.	Determine the kinetic energy of a circular disc rotating with a speed of 60 rpm about an axis passing through a point on its circumference and perpendicular to its plane. The circular disc has a mass of 5 kg and radius 1 m.
Answer» SOLUTION :KINETIC ENERGY K.E. `=(1)/(2)I omega^(2)=(1)/(2).(3MR^(2))/(2).(2pi)^(2)` `= 148.1 J`.
