## Homework Statement

2 crates shown in the figure below are on a horizontal frictionless surface. The woman is wearing golf shoes for traction as she applies a horizontal force of f= 50.0 N to the 6.00kg crate. The ropes are of negligible mass.

a) draw a free body diagram for each of the crates and the woman and for each force, indicate what body exerts that force.

b) What is the acceleration of the 6.00kg crate?

c) what is the tension T in the rope connecting the 2 crates.

## Homework Equations

F= ma

I don't know the equation for tension though...

## The Attempt at a Solution

Well would the free body diagram show the forces going in different directions?

I assume so but for the other box and woman how would that look?

b.) F= ma

I know it's that equation but how do I find out how much is the acceleration since there are 2 boxes but I have to find the acceleration of the first one?

do I add the masses and assume that the acceleration is the same for both? I think that it would be logical ..so

F= 50N

a=?

m= smaller box + larger box = 4.00kg + 6.00kg= 10.00kg= 10,000g

F= ma

50N= 10,000g*a

a= 5e-3m/s^2

Is this correct?

c.) for this part I have no idea how to find tension since it wasn't explained in class.

~Thanks~

P.S I really need to do this question by today...
