No. V=v0 +at is the formula for velocity, the acceleration 'a' can be the same but the initial velocity v0 may be different. If v0 is the same for the two automobiles , the velocity would be the same.
No, although they are accelerating (a) at the same speed their inital velocity (u) is undefined, therefore they may be getting faster at the same acelleration altough they may be at a different velocity to start with.
a = (u-v)/t (t = time, v= final velocity)
Yes, but not the other way round.
If the two cars have the same velocity, both their speeds and the directions in which they move will be the same.
Nope cause they got different mass.
Momentum is velocity times mass, so, in order for two cars to have the same momentum at the same velocity, they must have the same mass. Engine capacity has nothing do do with the equation.
A high speed collision between two cars would cause more damage than a low speed collision between the same two cars because they have more kinetic energy as their velocity increases. The greater the kinetic energy upon impact, the greater the resultant damage.
They would be traveling at the same speed. Two objects moving with the same velocity must be moving in the same direction and at the same speed. The reason for this is because velocity is speed in a specified direction. Another way to say that is to say that velocity is speed with a direction vector. It is a physical quantity with magnitude and direction. Two objects moving with the same speed could be moving toward a head-on collision. Or they could be moving along convergent, divergent or skewed paths. Not so with two objects that have identical velocities. They are moving on the same or on parallel courses, and they are moving at the same speed.
=== === Since momentum is a vector and not a scalar quantity, to have the same momentum, they must have the same direction. Remember, vectors have magnitude and direction. Speed is the magnitude part of velocity. Since momentum is the product of mass (a scalar) and velocity (a vector) if two objects are moving in different directions, even if they have the same mass and speed, their momentums are different.
The larger the mass a car effects the velocity in that you require a stronger engine to make it accelerate at the same speed of a lighter car. Having a higher mass, it will take longer for it accelerate as well as for it to decelerate. Two cars that collide that have the same velocity and masses will stop, while if ones mass his higher it will cause greater damage to the smaller one.
Yes. If they are traveling in the same direction and at the same speed, then they have the same velocity.
No, because velocity includes direction as well as speed.In order for the velocities to be the same, they would have to go the same speed in the same direction.

No, they don't. Velocity is a vector - made up of both a magnitude (number), and a direction. If any of the two changes, the velocity is not the same. If you are interested only in the magnitude, you talk about "speed", not "velocity".
No. Velocity is the combination of a speed and its direction. In order fortwo objects to have the same velocity, they must be moving at the samespeed, and in the same direction.
A high speed collision between two cars would cause more damage than a low speed collision between the same two cars because they have more kinetic energy as their velocity increases. The greater the kinetic energy upon impact, the greater the resultant damage.
Not necessarily. Velocity is made up of speed and direction, so if they go in different directions, their velocity won't be the same.
only if they are the same size
No. The speed is the same, the velocity is not. The term "velocity" includes the indication of the direction. Two velocities are the same if they have the same magnitude (e.g., both are 40 km/hour), AND the same direction.No. The speed is the same, the velocity is not.

Speed is a scalar, velocity is a vector. Two objects moving at the same speed but in opposite directions will have opposite velocities. If the velocity of the elevator going up is v, the velocity of the elevator going down will be -v.
