Question

5. A swing ride at a carnival consists of chairs that are swung in a circle by 11.5-m cables attached to a vertical rotating pole, as the drawing shows. Suppose the total mass of a chair and its occupant is 162 kg, the angle θ = 61°. Find the speed of the chair.

m/s

Step 1

Let us draw the free body diagram

Step 2

The equilibrium equations for the free body diagram are as follows:

Step 3

As, the length of the cable is given, we can use that to calcul...
