Question
In the International Space Station which orbits Earth, astronauts experience apparent weightlessness because _ The station is so far away from the center of the Earth The station is kept in orbit by a centrifugal force that counteracts the Earth's gravity _ The astronauts and the station are in free fall towards the center of the Earth There is no gravity in space The station's high speed nullifies the effects of gravity A space shuttle in orbit around the Earth carries its payload with its mechanical arm. Suddenly, the arm malfunctions and releases the payload. What will happen to the payload? It will fall straight down and hit the Earth. It will follow a curved path and eventually hit the Earth. It will remain in the same orbit with the shuttle. It will drift out into deep space. The curved section of a horizontal highway is a circular unbanked arc of radius 740 m. If the coefficient of static friction between this roadway and typical tires is 0.40, what would be the maximum safe driving speed for this horizontal curved section of highway?Explanation / Answer
11) C) The astronauts and the station are in free fall towards the center of the earth.
12) c) It will remain in the same orbit with the shuttle
13) a) 54 m/s
14) e) 19 m/s
17) a) 0.047 kg.m/s towards the right
18) d) 5.33 m/s
19) b) 3.5 m/s
