ANSWER:
Solution 2DQ
Acceleration is a vector,with units of
Acceleration indicates the rate of change of object's velocity,that is the acceleration tells you how fast the object's velocity is changing.
The component of acceleration that is parallel to velocity indicates that the rate of change of object’s speed.
If is parallel to the velocity,then object speeding up, if it is anti-parallel to the velocity,then the objects is slowing down.
