Homework Statement
Hi Everyone would somebody please be able to give some advice on the following questions:
Part (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.
I have attached a solution does it look right or is there a more efficient way to calculate it?
Part (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.
I'm a little bit stuck any idea what formula I would use to begin to solve it? Thanks in advance
