(adsbygoogle = window.adsbygoogle || []).push({}); (1)A "swing" ride at a carnival consists of chairs that are swung in a circle by 10.0 m cables attached to a vertical rotating pole at an angle of 60 degrees with respect to the pole. Suppose the total mass of a chair and its occupant is 200 kg. (a) Determine the tension in the cable attached to the chair. (b) Find the speed of the chair.

(2)At an amusement park there is a ride in which cylindrically shaped chambers spin around a central axis. People sit in seats facing the axis, their backs against the outer wall. At one instant the outer wall moves at a speed of 3.62 m/s, and an 88.9-kg person feels a 507-N force pressing against his back. What is the radius of a chamber?

ƩF=ma

a(centripetal)=v^2/r

Can anybody help me with how to start negotiating this problem? I'm not sure how to begin. I was taught to draw free body diagrams first but that doesn't seem to get me anywhere.
