Question

If the average speed of an orbiting space shuttle is 27 800 km/h, determine the time required for it to circle Earth. Assume that the shuttle is orbiting about 320.0 km above Earthâs surface, and that Earthâs radius is 6380 km.

Answer 1

Answer:

 t = 1.51 hours

Explanation:

given,

Speed of space shuttle. v = 27800 Km/h

Radius of earth, R = 6380 Km

height of shuttle above earth, h = 320 Km

Total radius of the shuttle orbit

r' = R + h

r' = 6380 + 320

r' = 6700 Km

distance, d = 2 π r

   d = 2 π x 6700

$time = \dfrac{distance}{speed}$

$time = \dfrac{2\pi\times 6700}{27800}$

 t = 1.51 hours

Time require by the shuttle to circle the earth is equal to 1.51 hr.
