Finding the coefficient of static friction in a centripiton force equation

AI Thread Summary
To find the coefficient of static friction preventing the laptop from sliding on the bus seat during a turn, the centripetal acceleration formula ac = v^2 / r is essential, where v is the velocity (10 m/s) and r is the radius of the turn (25 m). The frictional force can be expressed as ff = μ * fn, where μ is the coefficient of static friction and fn is the normal force. A free-body diagram can help visualize the forces acting on the laptop, aiding in the setup of the equations. The sum of forces in the horizontal direction must equal the mass times the centripetal acceleration. Ultimately, solving these equations will yield the required coefficient of static friction.

Homework Statement




a bus passanger has her laptop sitting on the seat next to her while the bus moves at 10m/s, the bus goes around a turn with a radius of 25m. what is the coefficient of static friction in order to keep the laptop from sliding?

Homework Equations





The Attempt at a Solution


ff=πfn
ac=v^2 /r
cant figure out the correct formula of formulas to use

It's a force problem, so ∑F=ma is a good one to consider using.

As with all force problems, start by drawing a free-body diagram.
 

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...
