Question

The space shuttle Endeavor is launched to altitude of 500 km above the surface of the earth. The shuttle travels at an average rate of 700 m/s. How long will it take for Endeavor to reach its orbit in minutes?

Answer 1

Average Velocity = V

Distance = D

Time = t

 

V = ΔD/Δt ; (700m/s) = (500km)/t 

 

t = 11.9 min with proper conversions
