W = (Mg)/6
2.94=M*9.8/6=M*1.63
THEREFORE M= 2.94/1.63=1.8 APPROX
ACTUAL WEIGHT = MG = 1.8*9.8 = 17.6 APPROX

The weight on the moon is just 1/6 that of the weight on earth.
Therefore, it is 2.94 x 9.8 / 6
= 4.802 approx.

Acceleration due to gravity on the surface of the moon, gm = 1.625 m/s2
Given that m*gm = 2.94 kg m/s2
Therefore, mass, m of the body is: 2.94 kg m/s2 / gm = 2.94 kg m/s2 / 1.625 m/s2 = 1.809 kg
So the actual weight = mg, where g is the acceleration due to gravity on the surface of the earth.
ACTUAL WEIGHT = m*g = 1.809 kg * 9.81 m/s2 = 17.75 kg m/s2

it is 2.94 kg on moon GIVEN
the body on earth is 6times then at of moon
2.94 * 6 WEIGHT
FOR MASS WE KNOW F=W = mg so g on earth is 9.8m/s^2
so 2.94*6/9.8
