Vectors have both size and direction.
Vectors are indicated with arrows.
Vectors can have positive or negative values.
Answer: A
Explanation: Neglecting air resistance every object will return to the ground at the same interval regardless of their weights, we can say that the objects are undergoing free falls, they are falling under the sole of gravity.
No matter the weight of the objects or the elevation, without significant air resistance, they will reach the ground at the same time.
It indicates that car is at rest at all time (t) :-)

Kent's ball will go in the direction that the ball is going right when he lets go of it.
Imagine this like an analog clock. 12 is forwards, 6 is behind, 3 is right, and 9 is left relative to Kent. If Kent is twirling the ball clockwise and lets go at 3, the, the ball will go behind him as the velocity vector exactly at 3 points behind Kent in a clockwise motion. Here are Kents velocity vectors according to my clock analogy. Hope this helps because this is how I learned it!
