Hi all, My problem is concerning density and how to calculate it. Basically, calculating density of a concrete cube. I've been given; Weight (kg) In Air - 2.345,2.340 In Water - 1.348, 1.360 Dimensions - Height - 1900mm Width - 320mm...

thanks a lot mate cheers si

ur hwk? no...its not even mine? i found this prb in the math book an thought it was impossible, u don't know 'mu'so i aint so sure on what to do, findin the coeficient of friction would help, or even having it would help! so its not possible without either of those two? cheers si

thankyou for your constructive replies, NateTG Well, for starters you've got the wrong magnitude for the normal force. ok fair enough say its wrong, but i don't see you correcting it? bout my description, ok I am trying to find the frictional force working against the block which is MOVING...

hey firstly, I am not so certain this is the correct place for this thread, sorry!feel free to move! basically, if you look at the file attached, I am trying to find friction up the slope, but i cannot do it, and i can't see how you will do it, so if anyone could shine some light, i would be...

chemicalsuperfreak thankyou very much helped a lot! :>:>:> all done now, cheers si
