A man can lift a mass of 200 kg on the surface of earth.what is the amount of mass he can lift on the moon?
Answers
To find the weight on the moon, we divide the weight on earth by the earth's force of gravity, which is 9.81m/s2. This calculates the massof the object. Once we have the object's mass, we can find the weight by multiplying it by the gravitational force, which it is subject to.
Answer: On the earth
Mass of the body on the earth (m1)= 200kg
Acceleration due to gravity of the earth (g) = 9.8
We have
Weight = m1 × 9.8
= 200x 9.8
= 1960N
On the moon
Again
Weight (w) = 1960 N
Mass of the moon (m2) = ?
Acceleration due to gravity on the moon (g2) = 1.67m/s2
We know that
W= m2 × g2
M2 = W / g2
M2 = 1960/1.67
= 1173.65 kg
Such person can lift 1173.65 kg mass on the moon
