Once the crate is sliding how hard do you push to keep is moving at constant valocity?

You need to push as much as the force of friction is.

How does the path of the crate appear to somebody on the airplane and to someone on the ground when a crate is dropped from an airplane flying horizontally at constant speed?
Person on the airplane: Crate will appear to be dropping straight down. Person on the ground: Crate will be curving in the direction the plane is moving.
Pull horizontally on a crate with a force of 140 N and it slides across the floor in a dynamic equilibrium How much friction is acting on the crate?
If the crate isn't accelerating ... i.e. sliding at a constant speed, not speeding up or slowing down ...then the forces on it are balanced. The pseudo-force of friction is 140N in the direction opposite toits speed.
A 1500 N crate is being pushed across a level floor at a constant speed. What will be the acceleration of the crate?
0 since the speed is constant
What is the net force on a crate sliding at an unchanging speed when pushed with a steady force of 75 N?
zero
If a crate weighing 508 N is resting on a plane inclined 26degrees above the horizontal if acceleration is 4.29 then how fast will the crate be moving after 6 seconds?
Impossible:)

If you push on a heavy crate to the right and it slides what is the direction of friction on the crate?
The direction of friction on the crate is opposite to the direction in which it is sliding. In this case, since you are pushing the crate to the right, the friction will act to the left in order to oppose the motion.
When crate training do you put the crate near you at night?
In my opinion you should start with the dog crate next to you, and start moving it away from you little by little.

What will happen at the exact moment a plane flies directly over a car the plane drops a crate where will the crate crash?
not on the car because they are not moving at the same speed
If a crate is stationary on an incline does it mean that it is in the state of equilibrium?
If a crate placed on an inclined plane is moving at constant velocity or not moving at all -- which is really a special case of constant velocity where the velocity is zero -- then the sum of the forces acting upon it is zero. We can say that it is in a state of equilibrium, where all forces acting upon it are in perfect balance and cancel themselves out. A free-body diagram is often used to represent a body and the forces acting upon it and helps us visualize the relationship of the vector forces. See this link: http://en.wikipedia.org/wiki/Free-body_diagram#Example
If a box is sliding along at a constant speed and the force of friction on the box is 100n what is the net force on the box?
If the box is sliding along at a constant speed, the net force acting on the box is zero.If the net force was not zero, the box would either be speeding up or slowing down.Non-zero net forces acting on objects cause the objects to accelerate. Therefore, if the net forces is not zero, the velocity of the object could not be constant.
A constant push of 250 N is needed to slide a crate that weighs 400 N along a 2 meter long ramp If the ramp raises the crate 1 meter what is the ramp's efficiency?
80%
A 40kg crate is at rest on a level surface if the coefficient of static friction between the crate and the surface is 0.69 what horizontal force is required to get the crate moving?
276 Newtons. Coefficient of static friction is a ratio between the force it takes to budge the object over the normal force (mass times gravity). So: 0.69 = Force / 400 N (40 kg times 10 m/s^2, the force of gravity). Solve for 276 N.
