Study the motion map shown. what do the circled vectors represent? a. velocity b. speed c. positive acceleration d. negative acceleration

It's option d - Negative acceleration

Explanation:

Mathematically position X , velocity V and acceleration A are:

and

Where X, V, A are vectors and  indicates the derivate a of a time is equal to b.

So, this show that acceleration is a rate respect of time of velocity ⇒ When acceleration is positive, velocity increments, when acceleration is negative, velocity decrements.

The above explanation correspond to the motion map shown, getting demonstrated that the answer is D - Negative acceleration
