[Mathcaptor]

Homework Statement

A woman has a mass of 75.0kg. What is her weight on earth?

Homework Equations

Unknown.

The Attempt at a Solution

I've been looking in my textbook for some kind of equation or a conversion, but I cannot find it.

 

[Doc Al]

Keep looking! (It has something to do with the acceleration due to gravity.)

Is it possible that it is W = m * a

 

[Doc Al]

Is it possible that it is W = m * a

Yes, where a = g.

I'm not really sure what g is. Would I have to find for that? Should I find the gravity of earth?

 

[Doc Al]

I'm not really sure what g is.

g is the acceleration due to gravity, a well-known constant (that I'm sure you're expected to know) that describes the strength of Earth's gravity near its surface. Read the link--it's there.

Oh, I see. It is 9.8 m/s^2!
