Answer:
1a) True 1b) False
Explanation:
The definition of a car's velocity is the change of displacement between time, from here we can see that this is a vector, this means that it has magnitude and direction.
The definition of speed is the change of distance between the unit of time, as we see this magnitude is a scalar since distance is a scalar.
1 a) the car has the same speed, True since the magnitude is a scalar
1 b) the cars have the same speed. False since the magnitude is a vector, even if it has the same module it has different direction
