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 perpedicular to its plane. The circular disc has a mass of 5kg and radius 1m.

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 perpedicular to its plane. The circular disc has a mass of 5kg and radius 1m.
Answer» SOLUTION :Kinetic ENERGY K.E`=(1)/(2)Iomega^(2)=(1)/(2).(3MR^(2))/(2).(2pi)^(2)` `=148.1J`
