We use the equation:
g = G m / r2
where
<span>G=constant universal gravitational = 6.67 x 10^-11 n m^2/kg^2 </span>
<span>m=planet mass=5.9736 x 10^24 kg (twice=11.9472) </span>
<span>r radium planet=6.372 km (twice=12.744)
</span>
<span>g= 6.67 x 10^-11 n m^2/kg^2 x 11.9472 10^24 kg/(12.744.000m)^2 </span>
<span>g=4.90 m/s^2 (1/2 of Earth gravity) <------- second option</span>
d = speed x time
distance = 29 x 30
distance = 870m
please mark as BRAINLIEST
I think it is (c) but I’m not 100% sure
