question

Which graph would match the same type of movement that the graph shows?

answer

A.)

question

What is the acceleration?

answer

0.2 m/s2

question

If the change in velocity increases, what happens to the acceleration during the same time period?

answer

Acceleration increases.

question

Based on the graph of velocity over time, which could be the initial velocity and the final velocity for this graph?

answer

initial = 2.5 m/s; final = 2.5 m/s

question

Ariana is accelerating her car at 4.6 m/s2. It took her 10 seconds to reach this acceleration. Her starting velocity was 0 m/s.
What was her final velocity?

answer

46 m/s

answer

wind
water movement
a hill
a stop light

question

direction.

question

Which best describes the riders?

answer

Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.

question

If velocity is positive, which would most likely yield a negative acceleration?

answer

An initial velocity that is faster than a final velocity.
