The Singapore Flyer is a giant observation wheel (similar to a Ferris wheel) that has 28 capsules and can hold a total of 784 passengers. The diameter of the wheel is 150 m and the entire thing rotates one complete revolution in 30 minutes. The rim weighs 7 x 10^5 kg, the capsules each weigh 1x 10^4 kg, and the average person weighs 70 kg. Calculate (a) the magnitude of the angular momentum at full capacity, and (b) the average net external torque applied to the spindle (axle) if it comes to a complete stop in 15 minutes. Write your answers using 3 significant digits.
