How do I answer part B?

5. (6 pts.) A Ferris wheel with a radius of 50 feet, with a center that sits 60 feet above the ground, turns at a rate of 2 revolutions per minute. That means it completes one full turn in = of a minute, so its period is = minute. One formula for the height above ground of a rider on this Ferris wheel is: H (t) = -50 cos(4xt) + 60. (a) Write a formula for H(t) using a sine function instead of a cosine function. (Note: The rider should still start at the lowest point on the ride at time ( = 0.) 0 0.25 0.5 0.75 1.25 (b) Write another formula so that at time t = 0, the rider starts the ride so that they're level with the wheel's center, at 60 feet above the ground. 0 9. 25 0-5 0-75 1 1.35
