Answer 2

Answer:

The escape velocity on the moon is $2.2 \ km/s$

Explanation:

The radius of the moon, R is $1600 \ km$.

Acceleration due to gravity on its surface, g is $1.6$ $ms^{-2}$

We know that escape velocity is given by,

$V_{e} = \sqrt{2gR}$

Substituting the values in the above equation we get,

$V_{e} = \sqrt{2 \times 1.6 \times 1600 \times 10^{3} } \\= \sqrt{2 \times 16 \times 16 \times 10^{4} } \\= 2262.7\ m/s\\= 2.2 \ km/s$

Hence, the escape velocity on the moon is $2.2 \ km/s$
