The abverage acceleration is a = (V^2)/2x = 35^2/(2*.11) = 5568.18 m/s^2\nMultiply this by the mass and you get the average force:\n\nFa = .14*5568.18 = 779.14 N

First you should draw a free-body diagram to understand the forces acting on the block.  In this case, you have 4 forces:\n\n1) 40 N force moving in the +x direction, let's denote it F_1\n2) frictional force moving in the -x direction, let's denote it F_2\n3) Weight, moving in the -y direction, let's denote it W\n4) Normal force opposing weight, let's denote it N\n\nNow you can write Newton's 2nd law equations:\n\nx-direction: F_1 - F_2 = m*a\ny-direction N - W = 0 (equal to zero because block does not move in this direction)\n\nUsing these equations, you know that N = W = m*g\n\nUsing F_2 = u*N and a = 6 m/s^2m, we can solve for thd desired variables:\n\na)\nF_2 = F_1 - m*a  ---------> 40 - (5)(6) ---------> F_2 = 10 N\n\nb)\nF_2 = u*N = u*m*g, now solve for u:\n\nu = F_2/(m*g) = (10)/(5*9.8) -----------> u = 0.204\n\n--------------\n\nHope this helps

Very simple, in your case you only need to convert from N(Newton) to Kg(kilogram) so just divide by 9.8 (gravity constant)\n\nN/m2---- /9.8 ---> Kg/m2\nN/m2<-- X9.8 ---- Kg/m2

C'mon, kid.  Go and read your book and do your homework.  I can understand if you are having problems with one problem, but you are posting this so that others will do your learning for you.  This is simple Newtonian physics.  Three laws you have to work with.  Basic, basic concepts.  If you can't handle this, then might as well give up your dreams of becoming a rocket scientist where you have to deal with special relativities and zero-gravity physics.  \n\nNow get moving!

it is the normal force per area...\nyou can visit this site:\nhttp://en.wikipedia.org/wiki/Pressure

The net external force acting on a particle is equal to the product of the mass and its acceleration.\n\nF = ma\nwhere, F = the net external force\n       m = the mass of the particle\n       a = the acceleration of the particle

this is the amount of force.  Force equals mass times acceleration.  The mass is ur bodyweight in kilos and the acceleration is gravity 9.8m/s/s

The total force on the block is mg sin (theta). The mg cos (theta) and force normal cancel out. Since there is no friction, the only force, again, is only mg sin (theta). \n\nThis is obvious if you consider that there is a force mg, and break it down into components, the solution should seem obvious.

Add up one opposite vector (going up). In physics, they call it NORMAL FORCE.

Newton: universal absolute time, 3 dimensional Cartesian geometry, action at a distance (force), universal gravitation as a force with an inverse-square law\n\nEinstein: relative time, non-Cartesian geometry, absolute limit to speed (speed of light), 4 dimensional space-time, gravitation as a result of the curvature of space and time.

try the formulas:\n\nforce = mass * aceleration\n\nwork = force * distance\n\n\n\n\nWell i dont speak english very well, but i hope i help u.\n\nKisses

Newton's Laws of Motion:\n\nI. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.  \n\nII. The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector.  \n\nIII. For every action there is an equal and opposite reaction.

Force = mass * acceleration\nForce = 1300 kg * 2.6 m/s2\nForce = 3380 Newtons
