well as we know that velocity is a vector hence it has magnitude as well as direction. Let us assign sign conventions for direction of velocities in this example: Let eastward velocity be positive and westward be taken as negative. Initial Velocity:-20 Final Velocity:+5 CHange in velocity=Final velocity-Initial Valocity Change in Velocity=5-(-20)=25m/s So change in velocity will be 25m/s

If a car is traveling westward with a constant velocity of 20meters per seconds what is the net external force acting on it?
It's zero
What will happen to an object moving at constant velocity?
Such an object is traveling at a constant speed in a straight line. Nothing will happen to it until the forces acting on it become unbalanced, or it runs into something.
What would the net force be on an object moving at constant velocity?
In order for an object to travel with constant velocity the sum of forces acting on it must be zero
How could you describe a situation where an object velocity does not change?
if velocity is constant, that means then the net acceleration acting on the object is equal to zero
What describes an object with constant velocity?
Constant speed, moving in a straight line, zero acceleration, zero net force acting on it.

It's zero
What is the net force on the different cars of a subway train that is traveling at constant velocity?
If anything is traveling at constant velocity, then the net force acting on it must be zero.+++Strictly, it is travelling at constant speed, not velocity, because you have not specified the directions of the train and the retarding forces acting on it.

What is the net force acting if your professor's car is traveling west with a constant velocity of 55 mi-hr west on a straight highway?
If the velocity of the object is constant, then the net force on it is zero.(Incidentally, if the velocity of the car is constant and not zero, then it must be ona straight highway. If the highway curved and the car's velocity didn't change, thenit would run off of the road.)
Can a body in equilibrium if it is in motion?
It can be in equilibrium if in constant motion (constant velocity) as no forces are acting on it (no acceleration)
If a cart is observed moving at a constant velocity along a horizontal frictionless track is there a constant net force acting on it in the direction of motion?
No force is acting on it. Constant velocity means no acceleration, which means no force, from f=ma, no 'a' no force.
If a body is moving with constant velocity is it moving with constant acceleration?
An object moves with constant velocity when there is no net force acting upon it. If there are no forces acting on an object, or if the forces acting on it "cancel out" leaving a net force of zero acting on the object, it will have zero acceleration. With a zero acceleration, the velocity of the object will be constant.
What can you assume if an object has a constant velocity?
The net force acting on it is zero.
What would the net force be on an object moving at constant velocity?
In order for an object to travel with constant velocity the sum of forces acting on it must be zero
What is the net force acting on a car cruising at a constant velocity of 70 kmh on a level road?
If the velocity is constant (no acceleration), the net force is zero.
If an object has no net force acting on it?
it is in equilibrium.
What are the conditions for an object to stay at restto keep moving at constant velocity?
"Constant velocity" means neither the speed nor the direction of the object's motion is changing. "Rest" is just one kind of constant velocity ... the kind with zero speed. The condition for an object's velocity to remain constant is: Either there are no forces acting on the object, or else all of the forces acting on it add up to zero. If there is any NET force acting on the object, then its velocity will change ... it will either speed up, slow down, or curve in a new direction.
