Question

erica is learning to drive, so her dad took her to a large, empty parking lot where she can practice. erica slowly starts driving, accelerating until she reaches and maintains a good speed. halfway across the lot, she stops briefly to practice braking. then, she repeats the process: accelerating, finding a good constant speed, and slowly coming to a stop. which graph could show ericas speed over time?

Explanation:

Step1: Analyze driving process

Erica starts from rest, so speed is 0 initially. Then she accelerates, speed increases.

Step2: Identify constant - speed phase

She reaches and maintains a good speed, so there is a horizontal part in the graph for constant speed.

Step3: Consider braking phase

She stops briefly to practice braking, speed decreases to 0. Then she repeats the process.

Answer:

The first graph (top - left) as it shows the initial acceleration, a period of constant speed, a decrease to 0 speed for braking, and then repeats this pattern.
