Question

The weight of a man on the surface of earth is 588N.find his mass,taking g=9.8.if the man was taken to the moon,his weight would be 98N.what will be his mass?

Answer 1

Answer:

Mass is 60 kg in both cases.

Explanation:

We know that,

Weight = Mass of the object × gravitational acceleration

Case 1.

Weight = 588 N, gravitational acceleration of earth = 9.8 m.s⁻²

Then 588 = M × 9.8,

where M is the mass of the man

or, M = 60

Therefore the mass of the man is 60 kg

Case 2.

The mass of the man is 60 kg on the surface of the moon, since the mass of an object never changes but the weight does due to different gravitational accelerations.

The gravitational acceleration of the moon is 1.625 m.s⁻². Then the weight of the object of mass 60 kg there be (60 × 1 625) = 98 N (approximately).

Answer 2

Explanation:

it would be 98 approx
