What is the size and direction of the final velocity of the tow cars if a 0.4 kg toy train car moving forward t 3 ms collides with and sticks to 0.8 kg toy car that is traveling in the opposite way?

0.4 kg(3 m/s) + 0.8kg(-2 m/s) = 1.2 kg m/s -1.6 kg m/s = -0.4 kg m/s
-0.4 kg m/s = 1.2 kg(v) = (-0.4 kg m/s)/(1.2 kg) = v = -0.33 m/s
the cars are traveling at 0.33 m/s in the direction of the second car.

Are you accelerating if you are traveling in a constant direction with constant speed and explain?
If you are traveling at a constant speed with changing direction there is a change in velocity, so you are accelerating.
When velocity is zero and acceleration is negative what happens to the object in motion?
It accelerates in the opposite direction. Its velocity increases in the opposite direction to the direction that has been assigned positive.
Can the velocity of object reverse direction when its acceleration is constant?
yes, if the acceleration is in the opposite direction of the velocity.
Can you cite an example in which the acceleration of a boby is opposite in direction to it's velocity?
Anytime an object is slowing down, its acceleration is in the opposite direction to its velocity.
Can momentum have a negative velocity?
No, momentum can not have a negative velocity. Velocity is the rate of motion of a body from one position to another position in a particular direction. Bodies traveling in opposite directions may appear to have a negative velocity in relationship to each other but any amount of velocity is positive.
Do Two cars traveling the same speed in opposite directions 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.
When angular velocity decreases the direction of angular acceleration is opposite to angular velocity .why?
Take the velocity to be in positive direction. Positive acceleration increases velocity and they are in the same direction. Negative acceleration reduce velocity and they are in opposite direction. It does not matter if the motion in linear or anfular.

The rate at which an object is traveling in a certain direction?
Velocity or Vector
Is velocity the rate at which an object is traveling in a certain direction?
Yes

Two buses depart from Chicago and going to New York and one to San Francisco. Each bus travels at a speed of 30ms. Do these buses have equal velocities explain.?
No the two buses do not have equal velocities because VELOCITY is the SPEED in a given DIRECTION. One would have a velocity of +30m/s because it is traveling in one direction, and the other would have a velocity of -30m/s because it is traveling in the opposite direction.
What is the velocity of a plane traveling northwest at 610 mph?
610 mph in the NorthWest direction. Both speed and direction are required to specify the velocity.
