The cosmoclock 21 ferris wheel in yokohama city, japan, has a diameter of 100 m. its name comes from its 60 arms, each of which can function as a second hand (so that it makes one revolution every 60 s).
part a: find the speed of the passengers when the ferris wheel is rotating at this rate (in m/s)
part b: a passenger weighs 834 n at the weight-guessing booth on the ground. what is his apparent weight at the highest point of the ferris wheel? (in n)
part c: what is his apparent weight at the lowest point on the ferris wheel?
part d: what would be the time for one revolution if the passeger's apparent weight at the highest point were zero? (in s)
part e: what then would be the passenger's apparent weight at the lowest point? (in n)

Determine the time it takes for a satellite to orbit the earth in a circular "near-earth" orbit. the definition of "near-earth" orbit is one which is at a height above the surface of the earth which is small compared to the radius of the earth, so that you may take the acceleration due to gravity as essentially the same as that on the surface. does your result depend on the mass of the satellite?
