Aspacecraft is coasting toward mars. the mass of mars is 6.00×1023kg, and its radius is 3.40×106m. when the spacecraft is 6.92×106m from the center of mars, the spaceraft's speed is 2910m/s. later, when the spacecraft is 4.09×106m from the center of mars, what is its speed?

4058.48594 m/s

Explanation:

M = Mass of Mars =

G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²

= Initial velocity = 2910 m/s

= Final velocity

m = Mass of satellite

= Initial distance of satellite =

= Final distance of satellite =

The kinetic and potential energy of the system is conserved

Final velocity is 4058.48594 m/s
