3. A Ferris wheel with a diameter of 140 meters is revolving in the biggest theme park in the world. The highest point of this Ferris wheel is 145 meters high! As the wheel is spinning, a skydiver named Joe drops onto the Ferris wheel where it is ascending 75 meters from the ground. The partial equation for the function is h(t) = 70 sin(kt) + 75 a. Suppose the Ferris wheel spins at a rate of 2 cycles every 180 seconds. Determine the value of K for the equation above. b. Using your completed equation, determine how high up Joe would be after 50 seconds, to the nearest metre.
