If the mass of an object is 6 lbm, what is its weight, in lbf, at a location where g = 32.0 ft/s2?

Using formula:

  -(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 = (given)

Now, substituting the values in equation (1):

Since,

So,

Hence, the mass of an object is 5.976 lbf.

b is the correct
