AI Thread Summary
To find the mass of the block being pushed with a 150N force and accelerating at 2.53m/s², the coefficient of kinetic friction is 0.15. The frictional force can be calculated using the formula F(friction) = F(gravity) * 0.15. A free body diagram is recommended to visualize the forces acting on the block, including the applied force and frictional force. The key equation to use is F = ma, where the net force is the difference between the applied force and the frictional force. The correct mass of the block is determined to be 38kg.

Homework Statement



Block is pushed across a horizontal surface with a coefficient of kinetic friction of 0.15 by applying a 150N horizontal force

the block accelerates at a rate of 2.53m/s^2 find the mass of the block

Homework Equations



Uf=ff/fn f=ma

The Attempt at a Solution



0.15=?/fn f=m2.53


I tried crazy solutions but no progress

The TB answer is 38kg. I have no idea what this 150N of force is, i tried using it as the net force or frictional force but it didnt work, what is it and what do i do?

0.15 is the coefficient of friction. So in this case the frictional force will be,

F(friction) = F(gravity)(.15)

Try drawing a free body diagram with the applied force (that's the 150N it's talking about) and the force of friction and try to figure it out. Remember 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...
