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
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!
