10. In Canada's wonderland, there is a roller coaster that is a continuous series of identical hills that are 18m high from the ground. The platform to get on the ride is on top of the first hill. It takes 3 seconds for the roller coaster to reach the bottom of the hill which is 2m off the ground. a. What is the cosine equation that best reflects this roller coaster's motion over time? (10, 13) (6/(૪)

Could you please explain A and B in more detail than the answer key shows? Thank you. 

10. In Canada's wonderland, there is a roller coaster that is a continuous series of identical hills that are
18m high from the ground. The platform to get on the ride is on top of the first hill. It takes 3 seconds
for the roller coaster to reach the bottom of the hill which is 2m off the ground.
a. What is the cosine equation that best reflects this roller coaster's motion over time?
(1018)
(6/l૪)
(-65, 10)
((1.5, 10)
Penod = 6
B= 20 = 11233
8 cos(x) +10
(3,2)
b. What is the sine equation that best reflects this roller coaster's motion over time?
8 sin = (x +1.5) +10
