The business terms push and pull originated in logistics and supply chain management, but are also widely used in marketing and in the hotel distribution business.
Walmart is an example of a company that uses the push vs. pull strategy.
A chain is held on a frictionless table with one-fourth of its length hanging over the edge. If the chain has length L= 28 cm and mass m=0.012 kg, how much work is required to pull the hanging part back onto the table?
I have used this model: W horizontal + Work due to gravity = Work...
After the London Bombings, American Forces have been told not to venture near the Capitol:http://news.bbc.co.uk/1/hi/uk/4673987.stm
Is this the first sign of 'Defeat' against terrorism?..or am I reading it wrong, maybe it's the first sign of Terrorism gaining the upperhand?
If London is...
A claw hammer is used to pull a nail out of a board. The nail is at an angle of 60 degrees to the board, and a force F1 of magnitude 500 N applied to the nail is required to pull it from the board. The hammer head contacts the board at point A, which is 0.080 m from where the nail enters the...
Hi everyone, sorry if I'm new to this and this subject have already been posted, but i have a test tomorrow, and i need help.
The question is that when the sun, the moon, and the Earth are in a straight line, with the moon is in between the sun and the earth. It is reasonable to think that the...
I think that the title of the topic is very self explanatory. I want to know what the explanation is for the different implementations, I reckon that it might have
something to do with the density of air and water.
an example problem statement
there is a rod and we pull one end of it with a 10N force with the other end fixed.
recall that a force acts on a body only when it accelerates. But in the above problem is it correct to say that 10N force is applied (i see
that there is no force applied on it...
anyone know the distance from Earth (to the moon) where the gravitational pull of the moon is equal to the gravitational pull of the earth? (or any way I could calculate it?) :confused:
A 12 kg sled is pulled along at a constant velocity on a horizintal surface by a horizontal force of 11N. How much horizontal force is needed to pull the sled at a constant velocity it two 57 kg girls are sitting in it?
How would I go about solving this?
Thanks, Amanda
A man is puling a box across the floor. Assume that the force of friction can be ignored and that the acceleration of the box is 1.27 m / s^2. Find the angle to the horizontal that the man must pull.
Given that the mass of the box is 15 kg. and the tension of the rope is 65N.
Hi
Lets say you have a 100' tree and you have the pull line going through a fork up the top. You have 2 options of where to tie it ...
A/ Tie to the top fork (running bowline etc)
B/ Tie off on trunk at base
My question is, is it the same?
Before you answer please consider that...
Please help me out with this question ...
While using a wheelbarrel to move heavy logs, you bump into a log laying across your path. Would it be easier to pull or push the wheelbarrel over the log blocking your path? And, why?
:smile:
What is the maximum pull a normal magnet (non electromagnet) of about the size of a computer mouse could achieve? And how would the cost of this compare to the cost of an electromagnet of the same pull? Also, will an electromagnet achieve it's desired pull immediately when the circuit is...
a horse pulls a barge along a canal using a rope 10m long. if the barge is 2m from the bank, the rope is taught and the tension in it is 500N. what are the components of this force at right angles to the canal?
i worked this out to be 99.7N i used 500 x sin 11.5 (the angle between the rope...
Suppose you are in a warzone. You are in a concealed position and there is only one enemy soldier nearby. Both you and the enemy soldier are conscripted soldiers, neither desired to join the army in the first place. Also suppose that this will be the enemy soldier's last day in active combat...
Force Question - Still want another oppinion!
A man pulls a cart on a friction fee surface by means of a pulley and rope. He pulls the rope at 600 N. Now replace the man's action with an iron weight of 60 kg so that it is attached to the end of the rope. The cart is again set in motion. Is...
If you have two particles that are even billions of light years away from each other, is there any gravitational pull between then? (Considering the possibility that there is nothing else in the universe)
I'm a _n^e_w^b_i^e (that looks cool :redface: ) in physics, and have many doubts about the current model of gravity.
I'm having a hard time viewing gravity as a pulling force. To me, it makes no sense. There is a new proposal, although very little have accepted it, on how gravity works...
Pull of Gravity...Where it starts?
hi...
Juz curious... when does the gravitational pull of Earth starts?
eg:
Let's say a comet/ a space rock ...It will travel slowly in space but once it is caught by gravity, it will accelerate, right? Yeah... so when does that happen.What distance from...
I was just thinking, and gravity, is the only invisible force that "pulls" everything else i can think of, besides magnetism, is a "push". can anyone else think of anything?
Quick questions for you astrophysicists out there:
At what velocity do objects typically "fall" towards the galactic center? Or are we talking a positive acceleration? Assuming the sun were to survive long enough to reach the center, which it of course won't, how long would it take? Or do...
Please Help! Tension Pull problem w/friction
Hello all, I am having a bit of trouble on this for some reason.
On a horizontal plane, a 10kg box and a 20kg box are tied together by a rope, and the 20kg box is being pulled by another rope with a force of 200N. The coefficient of friction is...
I need to calculate the force required to pull a copper ball radius 2.00cm upward through a fluid at the constant speed 9.00cm/s. The drag forse is to be proportional to the speed, with proportionality constant .950kg/s. Ignore any boyant force.
What I did so far was figure out the resistive...
Q: There is a mass of a mass A (2kg ) sitting on top of a mass of B ( 4kg), which is sitting on top of a mass of C(3 kg). The static friction between A and B is .5; and between B and C is .5 and between C and the ground is .8. Mass B is tied to the wall. What is the minium force required to...
