You already answered the question. Both cars are traveling at 70kmph, which is the same velocity.

You are in a car going 70 kmh and another car passes you going in the opposite direction at 70 kmh. do both cars have the same velocity?
No. Velocity is a vector, so it has both a magnitude and a direction. If the velocity of your car was heading in the positive direction, then the other car is moving in the negative direction. The velocities are NOT the same!
The speedometer of a car moving to the east reads 100km per hr and it passes another car that moves to the west at 100km per hr so do both cars have the same velocity please explain?
Velocity is direction and speed so the vehicle do not have the same velocity
What is the result if you subtract a velocity vector to another velocity vector?
The result will also be a velocity vector. Draw the first vector. From its tip draw the negative of the second vector ( ie a vector with the same magnitude but opposite direction). The the resultant would be the vector with the same starting point as the first vector and the same endpoint as the second. If the two vectors are equal but opposite, you end up with the null velocity vector.
One object has a velocity of -4 feet per second another has 3 feet per second which is greater?
The object with the velocity of -4 feet per second is going faster than the other, but in the opposite direction, hence the minus sign.
When an object's initial velocity is less than its final velocity what does that indicate?
AccelerationWhen the velocity of an object increases or decreases, that means it has accelerated. Acceleration is defined as the rate of change of velocity.If an object's final velocity is greater than its initial velocity, that indicates positive acceleration. If an object's final velocity is less than its initial velocity -- if, say, it slows down and comes to a stop -- then that indicates negative acceleration. Deceleration is another way of saying negative acceleration. But . . .It is good idea to avoid using the term deceleration, because an object that is experiencing negative acceleration may slow down, come to a stop momentarily, and then reverse direction and speed up -- IN THE OPPOSITE DIRECTION!You can think of it this way: When an object is slowing down, its acceleration is in the direction opposite to its motion. We think of that as negative acceleration.
You are in a car going 70 km per hour and another car passes you going in the opposite direction at 70 km per hour Do both cars have the same velocity Explain?
No. Since velocity is a vector, the direction of the magnitude (speed) is also relevent. First which car is moving in a positive direction (either is correct) --- v = +70 km/h. Since the other car is moving in the opposite direction, its velocity is -70 km/h.

Why can velocity be positive or negitave?
Velocity is a vector quantity that includes both magnitude (speed) and direction. Positive velocity indicates motion in one direction, while negative velocity indicates motion in the opposite direction. It reflects the rate of change of an object's position with respect to time.
Can momentum have a negative velocity?
Yes, momentum can have a negative velocity. Momentum is a vector quantity, meaning it has both magnitude and direction. A negative velocity indicates that the object is moving in the opposite direction of the chosen coordinate system, resulting in momentum with a negative velocity component.
What is another word for measure of speed and direction?
Velocity A Vector is the measurement of velocity and direction.
Is the velocity of 3ms greater than -4ms mathematically?
No. If you are talking about "velocity", then you are talking about magnitude and direction - i.e., vectors. You can't really compare vectors, in the sense of one vector being greater than another; but you can compare their magnitudes - and the magnitude is always non-negative. In this sense, you can't even have a "velocity of minus 4 m/s" - you would have a "velocity of 4 m/s in a certain direction".

The object with the velocity of -4 feet per second is going faster than the other, but in the opposite direction, hence the minus sign.
When we subtract a velocity vector from another velocity vector the result is?
The result of subtracting one velocity vector from another velocity vector is a new velocity vector. This new vector represents the difference in speed and direction between the two original velocity vectors.
What happens to the velocity when an object is accelerated?
When an object is accelerated, its velocity changes. The velocity can increase if the object is accelerating in the direction of its initial velocity, or decrease if the object is decelerating or accelerating in the opposite direction. The change in velocity is directly proportional to the acceleration applied to the object.
Does velocity indicates how long it takes to get from one place to another?
Velocity indicates the speed and direction of an object's movement but does not directly indicate how long it will take to travel from one place to another. Time taken for travel depends on distance, velocity, and any changes in speed or direction.
