Hello, mathaddict!

Juliana gets into the seat at the bottom of a Ferris wheel 1.5 m above the ground.
The radius of the Ferris wheel is m and it rotates in an CCW direction.

(a) Find the height, , of Juliana from the ground when the Ferris wheel stops
after rotating 300°. (Give your answer in terms of r.)
