Calculate the escape velocity of a body from the moon.
[ g( moon) = 1 .67 ` m//s^(2)` , R( moon) = ` 1.74 xx 10^(6) m` ]

Explanation

Data : ` g = 1.67 m//s^(2) , R = 1.74 xx 10^(6) m`
The escape velocity of a body from the moon,
` v_(ese) = sqrt(2gR) = sqrt(2 xx 1.67 m//s^(2) xx 1.74 xx 10^(6)m)`
` = 2.411 xx 10^(3) m//s = 2.411 km//s`
