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, first determine the block's actual acceleration using the distance and time provided. Next, apply Newton's second law to find the total force acting on the block. From the total force, calculate the frictional force opposing the motion. Finally, use the frictional force and the normal force to find the coefficient of kinetic friction. This method combines geometry and physics for an accurate calculation.

Homework Statement


A 3.6 kg block slides down an inclined plane
that makes an angle of 27
◦
with the horizontal.
Starting from rest, the block slides a distance
of 2.4 m in 6.2 s.
The acceleration of gravity is 9.81 m/s

.
Find the coefficient of kinetic friction between the block and plane.


I've asked other friends for help but they couldn't figure it out.

Hi FilibertoG! Welcome to PF! :smile:

(you'll find a ° in the Quick Symbols box next to the Reply box :wink:)

Do the geometry first, then the physics.

Use the data given to find the actual acceleration (that's the geometry part).

Then use that value of acceleration to find the total force, and from that find the fricton force.

Show us what you get. :smile:​
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
