An example of zero acceleration would be what?
If you are moving at a speed of ceratin speed and there is no force trying to slow you down, and there is no force trying to speed you up. Then there is zero acceleration. An example would be : an object in out in space, if you throw a object away from you the object will float away, since there is no force working on the object after you throw it the object is moving away in a locked speed from you, but have zero acceleration because there is no force affecting the object
If a car is moving at a steady speed of 50 mph what forces will be acting on it?
65
What is the net force on a crate sliding at an unchanging speed when pushed with a steady force of 75 N?
zero
A passenger in the rear car of a train moving at a steady speed is at rest relative to?
The train.
A glider sailing across the sky at a steady speed and altitude an example of and unbalanced force?
No. A glider that is moving at a constant speed and in a constant direction is at a constant velocity. In other words it is not accelerating. Therefore, all forces on it must be balanced.
Why does a car need energy to move at a steady speed?
A car needs energy to move at a steady speed because it needs to equalize the force of air pressure by moving forward.
What is the net force on a car traveling along a straight road at a steady speed of 100?
The term "steady speed" indicates a constant velocity. This implies that there is no net acceleration, and thus no net force. Any net force on a moving object will cause a change in velocity, as per Newton's First and Second Laws.

How can an object be motionless and in equilibruim?
an object that is not moving can be in equilibrum. an object moving at a steady speed in a straight line can also be equilibrum.
A glider sailing across the sky at a steady speed and altitude an example of and unbalanced force?
No. A glider that is moving at a constant speed and in a constant direction is at a constant velocity. In other words it is not accelerating. Therefore, all forces on it must be balanced.
What is the name of the speed at which a rocket can overcome the force of gravity?
Moving Speed, once the rocket is even moving 0.00000001 mph it is overcoming the force of gravity.
What do the arrows look like on a picture of a car moving at a steady speed?
They will be of the same length and size.
What is the net force of a car traveling at a steady speed of 100km per hour?
100
How do you compute the force of a given mass at a constant speed?
The force on a mass moving at a constant speed and direction is 0.
