Need help on this please folks, it has got me stumped.
1. 1. A body of mass m kg is attached to a point by string of length 1.25m. If the mass is rotating in a horizontal circle 0.75m below the point of attachement, calculate its angular velocity.
2. If the mass rotates on a table, calculate the force on the table when the speed of rotation is 25rpm and the mass is 6kg.
