Calculate the force on the table

  1. Apr 20, 2009 #1
    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.
