Question:
The radius of a neutron star is 750 times smaller than the Earth's radius, and its mass is 1.8 times larger than the Earth's mass. What is the escape velocity from the surface of a neutron star? (Ignore the fact that, at high speeds, one should not really use mv^2/2 for the kinetic energy.)
If my calculations are correct:
Rn=-4.7711x10^9 m
Mn= 1.0757x10^30 kg
I know that E= K + U in whick K is mv^2/2 and U = GmM/R but don't know how to advance, please help
Does vesc= square root of (2GMn/Rn) ?
