Find Coefficient of Friction: Force of Friction Homework

AI Thread Summary
To find the coefficient of friction (μ), the force of friction (Ff) must be determined using the equation Ff = μ(Fn), where Fn is the normal force. Given the mass of 0.034 kg and acceleration of -0.3644 m/s², the force can be calculated using F = m*a. The normal force on a flat surface equals the weight of the object, which is Fn = mass * gravity. Without specific values for Ff, the coefficients of friction for oil, water, and a dry surface must be referenced from tables. Understanding these relationships is crucial for solving the problem effectively.

Homework Statement


Mass: .034kg
Acceleration: -.3644
Time:2.744sec
Inital Velocity: 1m/s
The path is on a flat surface

Homework Equations


Ff=mu(Fn)
F=m*a

The Attempt at a Solution


I need help find the coefficient of friction. I'm trying to find the difference of mu between oil, water, and a dry surface, and I lack Ff, or I do not know how to find it without mu. Is there anyway to find the solution. Thank you

Unless you were given varying information for each case, you'd need to look those μ values up in a table

You know the mass and the acceleration.
What/who's law relates Force, mass and acceleration?
 

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...

Figure 1 Overall Structure Diagram Figure 2: Top view of the piston when it is cylindrical A circular opening is created at a height of 5 meters above the water surface. Inside this opening is a sleeve-type piston with a cross-sectional area of 1 square meter. The piston is pulled to the right at a constant speed. The pulling force is（Figure 2）： F = ρshg = 1000 × 1 × 5 × 10 = 50,000 N. Figure 3: Modifying the structure to incorporate a fixed internal piston When I modify the piston...

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...
