take weights of five of your friends find out what their weights will be on tha moon and tha mars
Answers
Answer:
The weights of 5 imaginary people, James, Ram, Jerry, Sarah and July in Earth are as given below.
James - 50 kg
Ram - 63 kg
Jerry - 45 kg
Sarah - 60 kg
July - 54 kg
Now, to find the weight of a person (or object) on another planet, we have to find his/her mass first. To do this, divide the person's weight on Earth by Earth's force of gravity which is 9.81 m/s². We get the following masses.
James - 50/9.81 = 5.1 kg
Ram - 63/9.81 = 6.4 kg
Jerry - 45/9.81 = 4.6 kg
Sarah - 60/9.81 = 6.1 kg
July - 54/9.81 = 5.5 kg
Now, to find the weight of the person on moon, multiply the mass by Moon's force of gravity which is 1.62 m/s². We get the following weights.
James - 5.1 x 1.62 = 8.3 kg
Ram - 6.4 x 1.62 = 10.4 kg
Jerry - 4.6 x 1.62 = 7.5 kg
Sarah - 6.1 x 1.62 = 9.9 kg
July - 5.5 x 1.62 = 8.9 kg
To find weight of these people on mars, multiply the mass by mar's force of gravity which is 3.711 m/s².
James = 18.9 kg
Ram = 23.8 kg
Jerry = 17.1 kg
Sarah = 22.6 kg
July = 20.4 kg
