Mr. Saurik proposed that the function h(t) = 6sin(3pi(t) - pi/3) + 5, where h(t) is in meters and t is in seconds, models the height above the ground of a point on a spinning wheel. Is Mr. Saurik's equation plausible? Explain.

I wonder how height can be negative when the sine function is -1
he means that when sin(x) = -1, your function gives 6(-1) + 5 = -1, so the point on the wheel is underground.

So, unless there's a trench, the equation is not plausible.
