AI Thread Summary
A blimp with a mass of 110 kg is being pulled downward at a 52-degree angle over a distance of 7 km while moving at a constant velocity of 14 m/s. The drag force acting on the blimp is calculated using the coefficient of drag, K, which is 0.5 kg/m. To determine the work done by the person pulling the blimp, it's essential to apply the work formula, F = w * d, and consider the forces acting on the blimp, including drag. A free-body diagram is recommended to visualize the forces involved. Understanding these concepts is crucial for solving the problem effectively.

Homework Statement


A blimp of mass 110 kg is pulled at an angle of 52 degrees downwards with respect to the horizontal for D=7 km on level ground at a constant velocity v=14 m/s. If the coefficient of drag (K in F=Kv^2) is 0.5 kg/m, how much work is done by the person pulling?


Homework Equations


F=w*d
F=Ky^2


The Attempt at a Solution


I don't even know where to begin! So confused.

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...
