h(t) = 125sin (pi/25t - pi/2) + 125

represents the height (h), in feet, of a seat on the wheel as a function of time (t), where t is measured in seconds. The ride begins when t = 0.

a.) During the first 50 seconds of the ride, at what time (t) is an individual on the Ferris Wheel exactly 125 feet above the ground?

attempt

125 = 125 sin pi(t/25 - 1/2) + 125, which is equivalent to

0 = sin pi(t/25 - 1/2)

pi(t/25 - 1/2) = k(pi), k an integer

t/25 - 1/2 = k

t/25 = k + 1/2

t = 25 ( k + 1/2 )

does this look right?

can anyone tell me where i should go from here?
