Homework Help Overview

The problem involves calculating the combined mass of a dog and a basket being lifted to a height of 5.05 m, given that 221 J of work is done in the process. The subject area relates to mechanics, specifically the concepts of work, force, and mass.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • The original poster attempts to apply the work formula but expresses uncertainty about how to derive the combined mass from the given information. Participants question the relationship between force and mass in the context of lifting the dog and basket.

Discussion Status

Participants are exploring the relationship between force, mass, and gravity. Some guidance has been provided regarding the definition of force in relation to mass and gravitational acceleration, but no consensus or final resolution has been reached.

Contextual Notes

The discussion includes a focus on the definitions and relationships between work, force, and mass, with an emphasis on gravitational effects. There is an implicit assumption that the acceleration due to gravity is understood and relevant to the calculations.

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?

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

I got it, Thanks!
