The acceleration due to gravity on Mars is 12.17 ft/s2. At sea-level on the Earth, an astronaut can lift an object that weighs 125 lbf. What is the mass of an object that the astronaut could lift on Mars?

Question

Given: gm = 12.17 ft/s2; We = 125 lbf;
Assume: ge = 32.174 ft/s2

Answer 1

Assume that the astronaut can continue to lift a weight equal to 125 lbf on Mars:
m = Wegc/gm = (125 lbf) (32.174 lbm-ft/lbf-s2)/(12.17 ft/s2) = 330 lbm
