yea, it should be 0.062395543 what now?

Homework Statement A cylindrical metal block of mass 32 kg stands with its base on a horizontal table. The radius of the base of the cylinder is 4 cm. Calculate the value of the pressure on the table. Homework Equations Pressure = Force/Area The Attempt at a Solution f = ma, i...

right, just how do i round that off to the si units thing and gneill, yea, pressure = force/area is what i meant, i know how to do these man, just need to know to get the answer to how it is in the actual book which is 2.613 x 104

Homework Statement Calculate pressure on the table caused by a block of mass 4 kg and acceleration due to gravity is 9.8 m s-2Homework Equations pressure = force/massThe Attempt at a Solution anyway, i get to, 39.2/(0.03)(0.05) and i get 26,133.33333 insteads of the actual answers which is...

well this is embarrassing, it took me having to draw a graph to realize where the origin was, and then it all came back to me...thanks

Homework Statement Find the slope of the line through x(2, -3) and y(1, 2). What is the slope of any line perpendicular to xy? Hence, find the equation of the line through the origin and which is perpendicular to xy. Homework Equations slope formula: m = y2 - y1/ x2 - x1...

i didn't no, but from the looks of it you multiply the whole number by the denominator and add the numerator so i got it, much appreciated

Homework Statement i just want to know how i go about it when the slope contains a whole number and a fraction, i.e. 1¼ Homework Equations y - y1 = m(x - x1) The Attempt at a Solution

oh...a = 0, *facepalm* tell me if I'm on the right path body1 [s = ut + ½at2] s = 40t + ½(0)t2 s = 40t and did you not mean (10 + t)? body2 [s = ut + ½at2] s = (0)t + ½2(10+t)2 s = (10 + t)2 and for the b formula b = u, a = a, c = 10 ?? -40 +- sqr402 - 4(2)(10)/ 2(2)...

hey gneill, i hate to waste your time like this on someones as clueless as me, so let's try and wrap it up just show me how you would go about doing it, your way, i'll learn from the whole thing, that's what i need, right now your killing me

what is do, i thought s= distance, also if do is distance what's the difference between do and d? im also guessing in these types of questions we won't be using the 3 formulas: [v = u + at], [s = ut + ½at2], [v2 = u2 + 2as] aw man, i think I am going to completely skip this question

nope
