It is zero. Do you see any difference between plus zero and minus zero?
gracy said:friction force= -0?
No.Not at all.Just edited.ehild said:Do you see any difference between plus zero and minus zero?
Just have a look at first questiongracy said:The answer should be 0.75.
I see. Then my drawing was wrong, why did you say it was correct ?gracy said:Just have a look at first question

WHY?ehild said:Then my drawing was wrong,
I thought It is just 2 blocks on inclined surface as my title indicates.ehild said:why did you say it was correct ?

Draw the FBD for the small block.
I help with a new picture, as nothing can be seen from yours. Note that m is on a horizontal surface!gracy said:
It is the resultant force on m. You know that it accelerates down the incline with a= gsin(37), so the resultant force is ma= mgsin(37).gracy said:From where mg sin theta is coming?component of mg?

ehild said:In physics problems, block is meant that : http://www.wdlconcrete.co.uk/images/blockmain-dense-midi.jpg
Yes, but a wedge was drawn, and the solution they provided counts with the wedge.gracy said:But the link I have provided says M is also a block.
You mean question is wrong?ehild said:Yes, but a wedge was drawn
How much time does it take to resolve a vector into two components, one horizontal and the other vertical?gracy said:Actually I am running out of time.
I have done this but not getting answer.Chestermiller said:How much time does it take to resolve a vector into two components, one horizontal and the other vertical?
Well tell us what you get for the two components of the acceleration.gracy said:I have done this but not getting answer.
I do not see that you gave the horizontal and vertical components of the force F=mgsin(37). Recall that force is parallel with the incline, so makes 37°angle with the horizontal.gracy said:I have done this but not getting answer.
