Question
A.Kamara 4. The graph below describes your height, h-ft), above the ground on a Ferris wheel, is in meters and t is time in minutes. You boarded the wheel before t- 0. Determine: a) Your position and direction at t 0That is, what o'clock?) b) How long it takes the wheel to complete one revolution c) The diameter of the wheel. d) At what height above the ground you board the wheel. e) The length of time the graph shows you riding the wheel. (2 pts) (2 pts) (2 pts) (2 pts) (2 pts) The boarding platform is level with the bottom of the wheel. 40+ 35 30 25 20t 15 10 1 2 3 45 67 89 10Explanation / Answer
A) As we boarded the wheel before t=0; we must be at some height now. The graph shows the height to be 35 meters and we can see that the height will decrease with time just after t=0. Hence we are at the TOP of the wheel and moving in downward direction.
B) We can say that the wheel makes a complete revolution when we reach the same point in the graph as we were at t=0; Hence we see that it takes 4 minutes for the wheel to complete a revolution
C) The diameter of the wheel is the difference between highest and lowest level of height that we traverse while on the wheel. We can see from the graph the diameter of the wheel will be 35-5 = 30 meters
D) At the time of boarding the wheel, our position will be lowest in terms of height. Hence we can say from the graph that we boarded the wheel at a height of 5 meters.
E) The graph shows our ride in the wheel for 10 minutes as the graph ends at time t=10 which means the ride ended and we deboarded the wheel.
