An iron ball is bobbing up and down on the end of a spring. The maximum height of the ball is 12 feet and its minimum height is 2 feet. It takes the ball 2 seconds to go from its maximum height to its minimum height.
Which model best represents the height, h, of the ball after t seconds?
h(t) = 5sin( πt / 2 ) + 7
h(t) = 5sin( πt ) + 7
h(t) = 10sin( πt ) + 5
h(t) = 12sin(πt / 2) + 2
