Calculate the force on the table

[bahramm]

Hi guys. I need some help to solve this question.

(a) A body of mass m kg is attached to a point by string of length
1.25 m. If the mass is rotating in a horizontal circle 0.75 m below the
point of attachment, calculate its angular velocity.

(b) If the mass rotates on a table, calculate the force on the table when
the speed of rotation is 25 rpm and the mass is 6 kg.

Hi bahramm,

Show us what you've done.

I got w^=g/h w=3.61 so far correct?

Yes that's the answer for part a.
