A circular space station of radius 100 m rotates twice each minute. a. Find the acceleration of an astronaut standing at the outer edge of the space

station. How many g's does she feel? (1 g = 9.8 m/s2

)

b. What must the period of rotation of the space station be in order for astronauts

at the outer edge to experience the same acceleration as on earth?

Henry, whose mass is 95 kg, stands on a bathroom scale in an elevator. the scale reads 830 n for the first 2.4 s after the elevator starts moving, then 930 n for the next 2.4 s. part a what is the elevator's speed 4.8 s after starting? express your answer with the appropriate units.

Identify the correct relation showing that the radius r of the orbit of a moon of a given planet can be determined from the radius r of the planet, the acceleration of gravity at the surface of the planet, and the time τ required by the moon to complete one full revolution about the planet. determine the acceleration of gravity at the surface of the planet jupiter knowing that r = 71 492 km and that t= 3.551 days and r= 670.9 × 10^3 km for its moon europa.
