What is the combined mass of the dog and basket?

  1. Nov 8, 2016 #1
    1. The problem statement, all variables and given/known data
    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. Relevant 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?

    If F is the force required to lift the dog and basket, how is F related to the mass of the dog and basket?

    Force/gravity = mass?

    Yes, if by "gravity" you mean free-fall acceleration due to gravity, g.
