At one time, Maple Leaf Village (which no longer exists) had North America’s largest Ferris wheel

At one time, Maple Leaf Village (which no longer exists) had North America’s largest Ferris wheel. The Ferris wheel had a diameter of 56 m, and one revolution took 2.5 min to complete. Riders could see Niagara Falls if they were higher than 50 m above the ground. Sketch three cycles of a graph that represents the height of a rider above the ground, as a function of time, if the rider gets on at a height of 0.5 m at t=0 min.Then determine the time intervals when the rider could see Niagara Falls
