OMG, WOW! IT WAS SO EASY! They are all the same?! I LOVE YOU!

if a = 0 , then F = fs ; which was already determined this seems like a loop to me

0, i think. a = F/m ; and net Force, F, is 0

it has to equal ma so... F - fs = m * a

Net Force = F - fs i think

so... would it simply be ranked based on the static frictional coefficient? the only other known variable is mass.

5 N. how would I figure out the horizontal force in this case? is this equation correct? F - μs(m * g) = 0 ; where F is the horizontal force

Ok, sooo F - μkmg = m * a there is no acceleration so F = μkmg So am I supposed to use μk instead of μs?

F=ma there is no acceleration because the crates do not move, correct? so force would be 0 for all of them? still a little confused.

Homework Statement Below are six crates at rest on level surfaces. The crates have different masses and the frictional coefficients [given as (μs, μk) ] between the crates and the surfaces differ. The same external force is applied to each crate, but none of the crates move. Rank the crates on...

ermm...i'm guessing m?

Homework Statement In the equation z = ct + d, z is measured in meters and t is measured in seconds. What are the dimensions (units) of d? answer options are... s/m, m/s, m, s, m*sHomework Equations The Attempt at a Solution plugged in m for z, s for t, and m/s for c. solved for D and got 0.
