Question

If the particle has mass m, how fast must it be moving away from the Sun's center of mass to escape the gravitational influence of the Sun? Express your answer to two significant digits and include the appropriate units.

Answer 1

Answer:

Explanation:

M = 1.989 x 10^30 kg

R = 6.96 x 10^8 m

G = 6.67 x 10^-11 Nm²/kg²

Let the velocity is v.

$v=\sqrt{\frac{2GM}{R}}$

$v=\sqrt{\frac{2\times 6.67\times 10^{-11}\times 1.989\times 10^{30}}{6.96\times 10^{8}}}$

v = 6.17 x 10^5 m/s
