Question

Calculate the weight of an object of mass 15Kg kept on the earth. If the same object is taken to mars, what change will happen to its mass and weight?(freefall acceleration on mars=3.7 m/s2)

Answer 1

Weight on Mars = 55.5 Newtons

Approximately 37.72% of weight on earth

Step-by-step explanation:

Mass of an object is unchanged throughout the universe

Therefore mass on Mars = mass on Earth = 15kg

Weight = mass x freefall acceleration

Weight on Earth = 15 kg x 9.81 m/s² = 147.15 Newtons (N)
Weight on Mars = 15 x 3.7 m/s² = 55.5 N

Therefore weight on Mars/ weight on earth = 55.5 N/147.15N

≈ 0.3772

= 37.72 % of weight on earth
