A)The mass of the Moon is 7.4 × 10²² kg, its radius is 1.74 × 10³ km, and it has no atmosphere. What is the acceleration (in m/s²) due to gravity at the surface of the Moon? (G = 6.67 × 10^-11 N ∙ m²/kg²)

B)From what height above the surface of the earth should an object be dropped to initially experience an acceleration of 0.54g? (G = 6.67 × 10^-11 N ∙ m²/kg², M_earth = 5.97 × 10²⁴ kg, R_earth = 6.38 × 10⁶ m)

C)A fairground ride spins its occupants inside a flying saucer-shaped container. If the horizontal circular path the riders follow has an 8.0 m radius, at how many revolutions per minute will the riders be subjected to a centripetal acceleration whose magnitude is 1.5 times that due to gravity?

D)An automobile with 0.260 m radius tires travels 83000 km before wearing them out. How many revolutions do the tires make, neglecting any backing up and any change in radius due to wear?
