What is the Average Force Required to Climb a Slope at Constant Speed?

AI Thread Summary
To determine the average force required to climb a slope at constant speed, one must consider the weight of the mass and the angle of the slope. The equation Ef = Fapp - Fgsin(theta) is relevant for calculating the applied force. The user expresses uncertainty about how to incorporate friction and speed into their calculations. They also acknowledge the forum's requirement to show an attempt at a solution before receiving assistance. Understanding the relationship between gravitational force and friction is crucial for solving this problem effectively.

Homework Statement



a 79kg mass can slide down a slope of 57 degrees at a constant speed of 12km/h/ how much average force must be abpplied to climb the hill at the same speed?

Homework Equations



Ef=ma
Ef=Fapp-Fgsintheta

The Attempt at a Solution



...ughm... kinda don't know how to start...?
but kk.. Fapp=Fgx+Ffs
but.. idk what mui is in Ffs...
so maybe.. Ffs = Fgx going down?

I don't know where to include the speed though...

Sorry, but forum rules state that we need to see an attempt at a solution first before we're allowed to help.

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'

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...
