Answer
(a) $4.81\;slugs$
(b) $70.18\;kg$
(c) $689.44\;N$
(d) $25.49\;lb$
(e) $70.18\;kg$
Work Step by Step
A man weighs $155$ $lb$ on earth: $W=155$ $lb$
(a) The mass of the man $=\frac{W}{g}=\frac{155\;lb}{32.2\;ft/t^2}\approx 4.81\;slugs$
(b) $1\;slug=14.59\;kg$
The mass of the man in $kg$ is given by
$=4.81\times14.59\;kg\approx 70.18\;kg$
(c) $1\;lb=4.448\;N$
The weight of the man in $newtons$ is given by
$=155\times4.448\;N=689.44\;N$
(d) Weight of the man in moon is
$W_m=mg_m=4.81\times5.30\;lb\approx25.49\;lb$
(e) Mass remains unchanged. Therefore mass the mass of the man in the moon is $70.18\;kg$
