Question

Part A Express your answer using two significant figures. Part B Express your answer using two significant figures. ?    = ? You are an astronaut in the space shuttle pursuing a satellite in need of repair. You are in a circular orbit of the same radius as the satellite (410 km above the Earth), but 30 km behind it. Part A How long will it take to overtake the satellite if you reduce your orbital radius by 1.2 km? Express your answer using two significant figures. t = h Part B By how much must you reduce your orbital radius to catch up in 5.5 h? Express your answer using two significant figures. Delta r = ? m

Explanation / Answer

vsat=31577.92 m/s
vshut=31621.43 m/s

vshut relative to satellite = 43.51 m/s

v=d/t => t=d/v

t = 20,000m / 43.51m/s = 459.66s = 0.13 hr
