Calculate the rotational energy of a segment, given mass of the segment is 2.2 kg, moment of inertia is 0.57 kg-m2, and angular velocity is 25 rad/s.

To solve this problem we will use the concepts given by the rotational kinetic energy which describes the energy in a body product of its moment of inertia and its angular velocity, mathematically this is given as,

Where,

I = Moment of Inertia

= Angular Velocity

Replacing with our values we have that,

Therefore the rotational energy is 178.125J

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

6 times more

wavelength divides in half and speed stays the same.
