A Ferris wheel has a 44-foot radius and the center of the Ferris wheel is 50 feet above the ground. The Ferris wheel rotates in the CCW direction at a constant angular speed of 3 radians per minute. Josh boards the Ferris wheel at the 3-o'clock position and rides the Ferris wheel for many rotations. Let tt represent the number of minutes since the ride started.Write an expression (in terms of t) to represent the number of radians Josh has swept out from the 3-o'clock position since the ride started.

How long does it take for Josh to complete one full revolution (rotation)?

________ minutes

Write an expression (in terms of t) to represent Josh's height above the center of the Ferris wheel (in feet).

Write a function f that determine's Josh's height above the ground (in feet) in terms of t.

f(t)=

There are 2pi radians in a full rev

2pi R/ 3 R/ min = 2/3 pi minutes per rev = 2.0944 min per rev

Period is 2/3 pi 2pi/x = 2/3 pi x = 3

soooo sin 3t

he starts at 3 o'clock position which is 1/2 way between low and high points....so there is no phase shift

Amplitude = 44 44 sin 3t = height above center

Height above ground IS shifted by 44 feet up from center 44 sin (3t) + 44 would be height above ground ( at time = 0 he is 44 ft above ground)
