Explanation:
According to Newtons second law,
F = m × a
where, F = force acting on object
m = mass of object
a = acceleration
On Earth, a = g
where, g = gravitational acceleration constant = 9.8 [tex]m/sec^{2}[/tex]
Now, convert g into [tex]ft/sec^{2}[/tex] as follows.
1 m = 3.280 ft
g = [tex]9.8 m/s^{2} \times 3.280 ft/m[/tex]
= 32.144 [tex]ft/s^{2}[/tex]
It is given that m = 148 lbm. Hence, calculate force as follows.
F = [tex]148 lbm \times 32.144 ft/s^{2}[/tex]
= 4757.312 [tex]lbm.ft/s^{2}[/tex]
= 4757.312 poundal
Thus, we can conclude that the weight in poundals of an 148 lbm object on Earth is 4757.312 poundal.
