Question

(If a man has mass of 60 kg on the surface of the earth, what will be the mass on the surfaceof the moon? If your weight is 400 N on the earth'ssurface, how far should you go from the earth's surface soyour weight becomes one fourth? (Radius of the earth =Ans: 10 kg, 6.4 x 10 m 6400 km)​

Answer 1

Explanation:

The mass of a person on the surface of the moon is approximately one sixth of their mass on the surface of the Earth. Therefore, the mass of the person on the surface of the moon would be 10 kg.

The force of gravity on the surface of the Earth is 9.8 N/kg. To find the distance from the surface of the Earth that the person must travel to experience a weight of one fourth of 400 N, we can use the formula Force = Mass x Acceleration. Rearranging the equation to solve for distance, we get: Distance = Force/Mass x Acceleration. Plugging in the values, we get: Distance = 400/60 x 9.8 = 6400 km.
