In summary, the children in the tree house lift a dog and basket 5.05 m up to their house, requiring 221 J of work. To find the combined mass of the dog and basket, the force required to lift them is divided by the free-fall acceleration due to gravity.

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?

Homework Equations


work(J)= force(N)x Distance(m)

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.

I got it, Thanks!
 

What is the combined mass of the dog and basket?

The combined mass of the dog and basket can be calculated by adding the individual masses of the dog and the basket together.

How do you determine the mass of the dog and basket?

The mass of the dog and basket can be determined by using a scale or balance to measure the weight of both objects separately.

Can the mass of the dog and basket be different in different environments?

Yes, the mass of the dog and basket can vary in different environments due to factors such as air density and gravitational pull.

What are the units of measurement for mass?

The standard unit of measurement for mass is kilograms (kg), but it can also be measured in grams (g) or pounds (lbs).

Is the combined mass of the dog and basket constant?

No, the combined mass of the dog and basket can change if the mass of either the dog or the basket changes, or if they are in a different environment.
