Physics Kinetic and Static fricton problem

AI Thread Summary
To move a 235 kg refrigerator, the force of static friction must first be calculated using the static coefficient of friction (μ = 0.535), which requires overcoming a force of approximately 1245 N. Once the refrigerator is in motion, the kinetic friction applies with a coefficient of 0.375, resulting in a force of about 880 N. With an applied force of 1250 N, the refrigerator can be moved after overcoming static friction. After it starts moving, the remaining force can be used to accelerate it, calculated using F=ma. This problem illustrates the difference between static and kinetic friction in practical applications.

You need to move a 235 kg refrigerator away from the wall to clean behind it. The sliding μ is .375 and the static μ is .535. You can apply a force of 1250 N.
a) How much force will it take to move the refrigerator.
b) Once it is moving, how fast can you accelerate it.

Can someone please explain step by step I don't even know where to begin with this problem.

You are given two different coefficients of friction, one for sliding (kinetic) and one for the initial movement (static).

More force is required to overcome friction initially for an object that is static than is required to continue the motion.

1) Try and calculate the force of static friction on the object with the static μ.

2) Since its moving calculate the force of kinetic friction on the object with the kinetic μ.
Now a little more work is required but just remember that F=ma.
 

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'

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...
