A fairground wheel is rotating in a vertical plane and carriages travel round a circle of diameter 40m at a constant speed. The carriages complete one revolution in 3.5min(adsbygoogle = window.adsbygoogle || []).push({});

I need to calculate the speed of the carriage from the top of the wheel to the bottom:

Circumference = 2 pi r

= 125.7m

top of wheel to bottom is therefore half this: 62.8m

Convert 3.5mins to seconds = 210s

half revolution = 105s

speed = distance/time = 62.8/105

speed = 0.6ms-1

I think this is right! :-s i'm a beginner!!

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

The problem i'm having is that i have to find the velocity aswell.....but am unsure how the distance affects the result in circular motion!

Please help me!!
