Question

Step 1

The weight of the astronaut on Earth is 700 N, the acceleration of the astronaut towards the moon is 1.62 m/s^{2} and the mass of the moon is 7.34×10^{22} kg.

Step 2

Weight on earth is mass times the gravitational acceleration on earth.

Let *W* be the weight of the astronaut on earth, *m*_{A} be the mass of the astronaut and *g* be the gravitational acceleration on earth.

Write the expression for the weight of the astronaut and rearrange for the mass of the astronaut

Step 3

Substitute 700 N for *W* and 9.8 m/s2 for *g* in the above eq...
