The graph below describes your height, hf0), above the ground on a Feris wheel, where h is in meters and I is time in minutes. You boarded the wheel before f0,and the boarding platform is level with the bottom of the wheel. (meters) (minutos) 15 30 What is your position and direction at t 0 How long does t take the wheel to complete one full revolution? minuteS What is the dameter of the wheel? meters At what height above the ground do you board the wheel? Ba

Solution

Wheel at t=0 has equlibrium postion

Means it has at half of position

But after t=0 the height of wheel decreases and at

t=0 postion is 15 meters so

After it decreses means goes to the zero height means at boarding platform so

1)the postion is 3PM and direction is clockwise

2)period = time taken in 1revolution

Here it take 15min to take same postion of graph from t=0 to t=15 minute

3) Diameter of wheel is 30

Because boarsing platform at zero postion mean height is zero and maximum height is 30 meter so diameter of wheel is 30meter
