Question

How much would a 60 kg man weigh on the moon? What will be his mass on the earth? (take gm = 1.6 m/s2 )​

Answer 1

Answer:

We’ve been given the mass of a man as 70 kg. We want to find his weight on the moon. We know that the weight of the man is calculated as

W=mg

Since the gravitational acceleration on the moon has been given to us =1.63m/s2

, the weight of the man on the moon will be

W=70×1.63

⇒W=114.1N

Hence the weight of the man on the moon will be 114.1 Newtons which is the actual unit of weight of the man.

Now the mass of the man will be constant irrespective of whether he is on the Earth or on the moon since mass is an intrinsic property of matter. Hence the mass of man on Earth and the moon will be 70 kg.
