A woman has a mass of 64.2 kg. What is her weight on earth?
Have you tried using W = M g?
If you use that formula, her mass will be in Newtons.
Don't you have a textbook?
To find the weight of a person on Earth, we can use the formula:
Weight = mass * acceleration due to gravity
The acceleration due to gravity on Earth is approximately 9.8 m/s^2.
Therefore, the woman's weight on Earth can be calculated as:
Weight = 64.2 kg * 9.8 m/s^2
Weight = 628.56 N
So, the woman's weight on Earth is approximately 628.56 Newtons.
