A"swing" ride at a carnival consists of chairs that are swung in a circle by 11.0 m cables attached to a vertical rotating pole, as the drawing shows. suppose the total mass of a chair and its occupant is 283 kg.
(a) determine the tension in the cable attached to the chair.
(b) find the speed of the chair.

a. tension of the cable attached to chair = 2.77kN

b. speed of the chair = 10.38m/s

Explanation:

A. tension of the cable is calculated by mass of the chair multiply by gravitational acceleration.

Tension(T) = m*g

where, m= 283kg

           length of cable = 11m

           and g=9.8m/s2

tension = mg = 283*9.8

            =2773.4 N = 2.77kN

b. speed of the chair =

= 10.38m/s

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
