To find out the weights of five friends on the moon and Mars, we need to first understand how the weight of an object changes in different gravitational environments.

On the moon, the gravitational acceleration is about 1/6th of the Earth's gravity, which means objects weigh only 1/6th of their weight on Earth. On the other hand, Mars has a gravitational acceleration of about 0.38 times that of Earth, which means objects weigh about 0.38 times their weight on Earth.

Let's assume the weights of our five friends on Earth are as follows:

  • Friend 1: 70 kg
  • Friend 2: 80 kg
  • Friend 3: 60 kg
  • Friend 4: 90 kg
  • Friend 5: 75 kg

Now, let's calculate their weights on the moon and Mars using the following formulas:

Weight on the moon = Weight on Earth / 6 Weight on Mars = Weight on Earth * 0.38

Using these formulas, we get the following weights:

Friend 1:

Weight on the moon = 70 / 6 = 11.67 kg Weight on Mars = 70 * 0.38 = 26.6 kg

Friend 2:

Weight on the moon = 80 / 6 = 13.33 kg Weight on Mars = 80 * 0.38 = 30.4 kg

Friend 3:

Weight on the moon = 60 / 6 = 10 kg Weight on Mars = 60 * 0.38 = 22.8 kg

Friend 4:

Weight on the moon = 90 / 6 = 15 kg Weight on Mars = 90 * 0.38 = 34.2 kg

Friend 5:

Weight on the moon = 75 / 6 = 12.5 kg Weight on Mars = 75 * 0.38 = 28.5 kg

Therefore, the weights of our five friends on the moon and Mars are as follows:

On the moon:

  • Friend 1: 11.67 kg
  • Friend 2: 13.33 kg
  • Friend 3: 10 kg
  • Friend 4: 15 kg
  • Friend 5: 12.5 kg

On Mars:

  • Friend 1: 26.6 kg
  • Friend 2: 30.4 kg
  • Friend 3: 22.8 kg
  • Friend 4: 34.2 kg
  • Friend 5: 28.5 kg

Take weights of five of your friend find out what their weights will be on the moon and the mars

Let the weights of my friends a,b,c,d,e  be  

45, 50, 40 , 36, 60 kg  respectively

Now,

We know that,  

weight of a person on moon=1/6 x weight on earth    

weight on moon:

a=1/6 x 45= 7.5 kg

b=1/6 x50= 8.34 kg  

c=1/6 x 40=6.67 kg

d=1/6 x 36=6 kg

e=1/6 x 60=10 kg
