# What is the combined mass of the dog and basket?

#### Angela_vaal

1. Homework Statement
Children in a tree house lift a small dog in a basket 5.05 m up to their house.
If it takes 221 J of work to do this, what is the combined mass of the dog and basket?

2. Homework Equations
work(J)= force(N)x Distance(m)

3. The Attempt at a Solution
W=FD........221J=F(5.05)m

I'm not sure how to start other than plug in the given variables with the equation I know. How would I get the combined mass?

Force/gravity = mass?
Yes, if by "gravity" you mean free-fall acceleration due to gravity, g.

Yes, if by "gravity" you mean free-fall acceleration due to gravity, g.
I got it, Thanks!
