Question #173141

The escape speed for a planet of mass M and radius R is 16.3 kms^-1.

Calculate the escape velocity from a planet of mass four times the mass and twice the radius.

Expert's answer

"v=\\sqrt{\\frac{2GM}{r}}\\\\v'=\\sqrt{\\frac{2G(4)M}{2r}}=\\sqrt{2}v\\\\v'=\\sqrt{2}16.3=23.1\\frac{km}{s}"
