Question

Please show work also. Thank You.

The Giant Swing at a county fair consists of a vertical central shaft with a number of horizontal arms attached at its upper end. Each arm supports a seat suspended from a 5 00m -long cable, the upper end of which is fastened to the arm. Take R = 2.10 .m Find the time of one revolution of the swing if the cable supporting the seat makes an angle of Theta = 36.0 degree with the vertical. t= Does the angle depend on the weight of the passenger for a given rate of revolution?

Explanation / Answer

g tan theta = v2 / (2.10 + 5 sin theta)

v = sqrt [9.8 * tan 36 * (2.10 + 5 sin theta) ] = 5.99 m/s

T = 2 pi r / v = (2 pi * (2.10 + 5 sin 36) ) / 5.99

= 5.29 s

-------------------------------------------

no

because we weren't ever given the specific weight or mass of the person

we found mg by using T cos 36 therefore the angle is not dependent on the weight.
