Coefficient of friction equations:

AI Thread Summary
A user is seeking assistance with calculating the coefficient of kinetic friction for a 4.40 kg block being pushed along a ceiling with a force of 89.0 N at a 66-degree angle, resulting in an acceleration of 6.80 m/s². They have provided the necessary values but are struggling to incorporate acceleration into their calculations. Suggestions include drawing a diagram and labeling the forces involved, as well as sharing their current equations and attempts for better guidance. The forum emphasizes the importance of showing work to receive further help. The user is encouraged to follow the guidelines for effective assistance.

i need help bad. i have a deadline that i need to complete very soon. please if anyone can help. i know i don't have the right answer:

a 4.40 kg block is pushed along the ceiling with a constant applied force of 89.0 N that acts at an angle of 66.0 degrees with the horizontal. the block accelerates to the right at 6.80 m/s^2. the acceleration of gravity is 9.81 m/s^2. what is the coefficeint of kinetic friction betweeen the block and the ceiling.

m = 4.4 kg
a = 6.80 m/s^2
fp = 89 N @ 66.0 degrees
g - 9.81 m/s^2

HELP

This is posted in the wrong forum. Do not double post, this one will be moved.

Well now that you've written all the known values. What can you do make your life easier in terms of getting to the formula? Mayb drawing a diagram and labeling? Mayb the 66 degrees is a give away that your diagram must include a triangle of some sort?
 
i have a diagram already. it does indeed form a triangle. i tried every equation i can think of and work out. i used the cos and sin to find the normal force and friction yet i don't know how to use the acceleration within the equations.
 
Perhaps you could post the diagram if possible and give us the equations you have so far. Please note that in order to receive further help, you must show your attempt(s) as per the guidelines.

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...
