Net Force and Applied Force: Calculating Acceleration and Friction Coefficients

AI Thread Summary
To calculate the acceleration and net force for the 11 kg block pushed with 45 N on a flat surface, first identify all acting forces, including friction. The coefficient of kinetic friction (0.12) will affect the net force and thus the acceleration. For the 12 kg box on the moon, the static friction coefficient (0.25) determines the force needed to initiate movement. It's essential to show your work and relevant equations to receive assistance in this forum. Understanding Newton's laws is crucial for solving these problems effectively.

Homework Statement



1.) An 11 kg block is being pushed forward on a flat surface with a force of magnitude 45 N. The coefficient of kinetic friction is 0.12 and the coefficient of static friction is 0.15. What is the accleration of the object, and what is the net force acting on the object?




2.) A 12 kg box is on the surface of the moon. The coefficient of static friction between the box and the surface is 0.25. How much force is needed to get the box moving?



-I'm just a little confused on how to put all of it together, I know bits and pieces, but a solution would be nice so I can refer back to it later. - Thanks

Hello, Verbally, welcome to Physics Forums!:smile:

As a newbie, you probably just glimpsed over the rules, which require you to list relevant equations and show an attempt at a solution before we can offer help. Solutions are not provided in this forum.

Try to identify all the forces acting on the block or box, and apply Newton's laws. Someone will then be glad to assist.

Thanks!:cool:
 

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'

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...
