It's been more than a day could anyone help me?

help?

I'm real rusty on my physics, but here are five simple sample problems we were given, I'd appreciate your help in helping me solve these. Thanks! Homework Statement (1) A single horizontal 10.0 N force, F acts on a 2.0 kg block which is initially at rest at x=0 m. In response to the force...

O.k. got it thanks! the sum of the x forces is: F-m1*a=3.4N or 4N-(1.5kg*.367347m/s^2)=3.4N and it is the same when you try the second mass: F+m2*a=3.4N or 2.2N+(3.4kg*.367347m/s^2)=3.4N Thanks for your help.

i do appreciate your help btw thank you.

it of course gives you force, the numbers represent my understanding of the words, I tried different combonations of adding subtracting and dividing mass, force and acceleration for the whole system but smartwork is telling me they are the wrong answers.

hmm..

f=ma (m1)1.5 (m2)3.4 (a).367347 (m1+m2)=4.9 (m1-m2)=1.8 1.5*.367347=nope 4.9*.367347=nope 1.8+.367347=nope lost.. what am i doing wrong?

Homework Statement Homework Equations f=ma The Attempt at a Solution I got the acceleration by: (f1-f2)/(m1+m2)=a Now the first two q's I just cannot figure out. 1.5*4=nope 1.5/.367347*4=nope 1.5/.367347+4=nope 4*.367347=nope 2.66667-.647059=nope......ah!

Homework Statement Homework Equations F=MA The Attempt at a Solution Weight M*G=55.5*9.81 Parallel force sin(30)544.455=272.228 Perpendicular force To Plane cos(30)544.455=471.512 Figured out that the man is pushing with a force of tan(30)544.455=314.341N Normal...

So AB would be straight down from initial point A? And what is the 3,4,5 triangle telling me? The proportions of PAB? If so then AB would be the 3 and PA would be the 5? What if I just did cos(30)*10, wouldn't that give me PB? Then I could do 250*PB. But I need the perpendicular don't...

What is PA? Point angle, I'm so confused.

I know how to do all the math, it is the conceptual part I don't have... can someone explain to me the picture in terms of the question??

Homework Statement Homework Equations Torque(n/m)=Force(N)*Length(L) Basic Trigonometry The Attempt at a Solution The concept of torque is new to me, so I just need a push in the right direction here. lbs and ft are used so we are using non-metric? Should I convert them to metric? How...

I appreciate your help! I did not solve this yet, I'll be back later, I actually have to run to physics class right now.
