The impact speed is just the difference between the two speeds, so in this case 2 km/hr.
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.
It is moving at 0.01944... (recurring) miles per second.
The bottom of the wheels.
Even though the space station is traveling at a speed of 17,500 miles per hour, all objects inside or attached to the space station are traveling in the same speed and direction. Relative to these objects, the space station will appear like it isn't moving at all. When an astronaut goes on an extra-vehicular activity (EVA) outside the space station, he will still be moving in the same speed and direction as the space station. Because of this, the space station will appear to be stationary to the astronaut (Unless the astronaut pushed against it, in which case the astronaut would drift away). In the event that an astronaut does accidentally push himself away from the space station, tethers and handrails allow the astronaut to pull himself back to safety.
moving a point or shape etc a distance in a certain direction
The impact speed is 100 - 98 = 2 kmh.
Whichever direction the traveling car was moving, until something stops them.
It slows to a rest and then starts moving in the opposite direction at constant acceleration in that direction.
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.

Velocity is a vector that has both magnitude and direction. Magnitude tells you how fast it is moving (speed) and direction tells you which way it is moving. For example car traveling at 60 mph due East has a sped of 60 mph and direction East. The combination of speed and direction is velocity.

No. 'Acceleration' means a change in speed or direction over time. If the car is moving at a constant speed in a constant direction, then it isn't accelerating.
forwards It is always traveling around the Earth in the same direction as we are rotating, but much faster. The space shuttle when in space can point in any direction, as there in no up and down. It still keeps moving in the same direction, even with engines facing forward.
yes
acceleration in a direction that is not parallel to the direction you are moving
