Question

24) b. Determine the escape speed of moon. Give the radius of moon is $1.74\times {10}^{6}m$ and its mass is $7.36\times {10}^{22}kg.$

Answer 1

Dear Student ,
The escape speed on the moon is ,
$v_e=\sqrt{\frac{2G{M}_m}{R_m}}=\sqrt{\frac{2\times 6·67\times {10}^{-11}\times 7·36\times {10}^{22}}{1·74\times {10}^6}}=2·375\times {10}^{3}m/s$
