[Punkyc7]

Homework Statement

A swing ride at a carnival consist of chairs that are swung in a circle by 15.0 meter cable that makes a 60 degree angle with a vertical pole. The mass of the chair and the occupant is 179 kg. Determine the tension in the cable. Find the speed of the chair

Homework Equations

F=(mv^2)/r F=mg

The Attempt at a Solution

So you draw a free body digram and the forces in the y are -179*10 and 179sin30 and the forces in the x is 179cos30. The radius is 15sin60. Thats about all i have.
