2. A man is 195 lbm on earth. How much does he weigh in lbfa) on Earth and b) on the moon if gravity is 5.32 ft/s2

Solution

mass of man = 195 lbm

gravity on earth =32.174 ft/s2

weight of man on earth = mg = 195*32.174=6273.93 lbf

gravity on moon = 5.32 ft/s2

weight of man on moon = 195*5.32=1037.4 lbf

note: W=1lbf=1lbm×32.174fts2
