Mae is checking her bicycle’s wheel. The wheel has a radius of 28 cm, and its center is 42 cm above the ground. Mae is rotating the wheel at a constant speed of 190°/s. The height of a point on the tire as a function of time is given by h = 42 + 28 sin(190t), where h is the height in centimeters, and t is the time in seconds. Find h when t = 2 s. Find your answer to the nearest tenth of a centimeter. a.
52.0 sm
b.
51.6 cm
c.
