Answer 2

Given:

• Weight on Moon ( w) = 750 N
• gravity on moon (g) = 1.6 m/s²

To Find:

• Mass of the body on the Moon?

Formula Used:

$\\ \bullet{\underline{\boxed{\sf\pink{ Weight = Mass \times acceleration \ due \ to \ gravity }}}}$

Solution:

After substituting values,

$\colon\implies{\sf{ 750 = M \times 1.6 }} \\ \\ \colon\implies{\sf{ \cancel{ \dfrac{750}{1.6} } = M }} \\ \\ \colon\implies{\sf{ M = 468.75 \ kg }}$

Hence,

The Mass of the body on moon is 468.75 kg.

Remarks:

• A = Acceleration
• W = Weight
• M = Mass
• SI unit of Mass is kilograms.
