The weight of an astronaut plus his space suit on the Moon is only 250 N. How much do they weigh on Earth? What is the mass on the Moon? On Earth?

Problem 13PE

Solution 13 PE

Step 1 of 4 :

In this question, we need weight of astronaut plus his suit on Earth

In the second part, we need to find the mass of astronaut plus his suit on moon

In third part, we need to find the mass of astronaut plus his suit on Earth

Data given

Weight on moon

Step 2 of 4 :

We should know gravitational force on moon

Weight is given by

Rearranging to find mass

Substituting values we get

Hence we have obtained mass as
