A kgf is the force required to accelerate a mass of 1 kgm at arate of 9.81 m/s2. A) what is the conversion factor to convert from mass unit toforce unit in this system. give its dimensions, and its numericalvalue and units. B) calculate the weight ( in kgf) of a 180 kg man (i) on mars(ii) on earth. A kgf is the force required to accelerate a mass of 1 kgm at arate of 9.81 m/s2.

B) calculate the weight ( in kgf) of a 180 kg man (i) on mars(ii) on earth.
Explanation / Answer
a) The convestion factorto convert from mass unit to force unit in this systemis 1 kgf = (9.81 m/s2)( kgm) b) The weight of the man on mars is W = mg' = (180 kg)(0.38)(9.8 m/s2) The weight of the man on earth is W =mg = (180 kg) (9.8 m/s2) Simplifying we get the answer.
