Question 685788: A person swings a small ball attached to a string around in a circle of radius 3 feet at a constant angular speed of 300 degrees per second. if the closest the distance the ball comes to the ground is 2 feet, which of the following functions best models the height, h, in feet, of the ball above ground as a function of the time, t, in seconds?
A) h = 3sin 300t + 2
B) h = 6sin 300t + 5
C) h = 3sin 300t + 5
D) h = 6sin 300t + 2

B) h = 6sin 300t + 5
C) h = 3sin 300t + 5
D) h = 6sin 300t + 2
------------------------
The amplitude = 3, so B & D are eliminated.
The minimum h = 2, so C is eliminated.
That leaves A.
