PLEASE HELP. The equation of a rider (in feet) above the ground after riding on the wheel for t seconds since passing the farthest right position on the wheel is given by h(t) = 30 sin(20t) + 40. Determine the height of the center of the wheel, period of rotation of the wheel, radius of the wheel, and angular speed of the wheel. Answer choices:

A. Center = 30 ft, Period = 20 sec, Radius = 40 ft, Angular Speed = 18 ft/sec
B. Center = 30 ft, Period = 18 sec, Radius = 40 ft, Angular speed 20 ft/sec
C. Center = 40 ft, Period = 20 sec, Radius = 30 ft, Angular Speed = 18 ft/sec
D. Center = 40 ft, Period = 18 sec, Radius = 30 ft, Angular Speed = 20 ft/sec
