Question

Use the velocity versus time graph below to answer the question. From 0 seconds to 15 seconds, what is true about the car?

A. It has a constant velocity

B. It has a negative acceleration

C. It has a positive acceleration

D. It is not moving

Answer 1

C

Step-by-step explanation:

The velocity is increasing steadily in this time frame

and represents a POSITIVE acceleration....

the acceleration would be equal to the slope of the line in that timeframe

Answer 2

C. Positive acceleration

Step-by-step explanation:

Since velocity increases each seconds, the acceleration will be constantly positive. Otherwise, if velocity decreases then acceleration will be negative. Pretty much like real-world application, when there’s (positive) acceleration, it goes faster.
