How Do You Calculate the Coefficient of Kinetic Friction on an Inclined Plane?

AI Thread Summary
To calculate the coefficient of kinetic friction on an inclined plane, start by identifying the forces acting on the mass, including gravitational force and friction. Use the equation Fnet = ma to establish the net force acting on the object. Determine the components of the gravitational force that are parallel and perpendicular to the inclined surface. The frictional force can be expressed as Ffriction = μN, where N represents the normal force. Understanding these concepts and equations is essential for solving the problem effectively.

I need help with a problem. In the book, the mass, the elevation of the inclined plane, and the acceleration are given. I am told to find the kinetic Friction coefficient. What equation(s) would I use to solve this problem?

You have to read more of the book than just the problems!:smile:

You'll need to understand Fnet = ma; you'll need to identify the forces acting on the mass; you'll need to find the components of those forces parallel and perpendicular to the surface of the plane; you'll need to understand that Ffriction = μN, where N is the normal force.

Have fun!
 
Thank you so soo soooooooo much!
 
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...
