Using formula:
[tex]w = m\times g[/tex] -(1)
where w is weight of object,
m is mass of the object, and
g is the acceleration of gravity.
mass, m = 6 lbm (given)
acceleration of gravity, g = [tex]32.0 ft/s^{2}[/tex] (given)
Now, substituting the values in equation (1):
[tex]w = 6 lbm \times 32 ft/s^{2} = 192 lbmft/s^{2}[/tex]
Since, [tex]1 lbf = 32.174 lbm ft/s^{2}[/tex]
So, [tex]w = 192\times \frac{1}{32.174 lbf}[/tex]
[tex]w = 5.976 lbf[/tex]
Hence, the mass of an object is 5.976 lbf.
