Aferris wheel of radius 100 feet is rotating at a constant angular speed Ο rad/sec counterclockwise. using a stopwatch, the rider finds it takes 5 seconds to go from the lowest point on the ride to a point q, which is level with the top of a 44 ft pole. assume the lowest point of the ride is 3 feet above ground level. let q(t)=(x(t),y(t)) be the coordinates of the rider at time t seconds; i. e., the parametric equations. assuming the rider begins at the lowest point on the wheel, then the parametric equations will have the form: x ( t ) = r c o s ( Ο t β Ο / 2 ) x(t)=rcos(ΟtβΟ/2) and y ( t ) = r s i n ( Ο t β Ο / 2 ) y(t)=rsin(ΟtβΟ/2) , where r,Ο can be determined from the information given. provide answers below accurate to 3 decimal places. (note: we have imposed a coordinate system so that the center of the ferris wheel is the origin. there are other ways to impose coordinates, leading to different parametric equations.) find r, find Ο. during the first revolution find the times when the riders height is 80ft.
