AI Thread Summary
To find the combined mass of the dog and basket, the equation for work done (W = F × D) is used, where W is the work in joules, F is the force in newtons, and D is the distance in meters. Given that 221 J of work is done to lift the dog and basket 5.05 m, the force can be calculated as F = W / D. The force is also related to mass through the equation F = m × g, where g is the acceleration due to gravity (approximately 9.81 m/s²). By substituting the force into the mass equation, the combined mass can be determined. The discussion concludes with the user expressing gratitude for the clarification.

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!
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
