Ask @ibrahimsakhawat:

A flywheel for a single piston engine rotates at an average speed of 1500 RPM. During half a rotation the flywheel has to absorb 1000 J of energy. If the maximum permissible speed fluctuation is ± 60 RPM, what is the minimum rotational inertia of the flywheel? Assume there is no friction

Oh bhai pehlai physics parh kar paghal hoa wa ho opper sai aap numerical pooch rahai ho
