Answer:
The correct answer is the option: B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.
Explanation:
Hello!
Let's solve this!
The options are as follows:
A. Gabriella is speeding up at the same rate that Kendall is slowing down, and Franklin is not accelerating.
B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.
C. Gabriella and Franklin are both slowing down, and Kendall is accelerating.
D. Gabriella is slowing down, and Kendall and Franklin are accelerating.
Looking at the table, we can say that:
Frank maintains the same speed, so neither speed nor acceleration changes.
In the case of Gabriela, we can calculate her acceleration which is:
a = vf-vi / t
a = (32-55) / 10
a = -2.3m / s2
This means that Gabriella is slowing down (because it is negative) at a rate of 2.3 m every second square.
In Kendall's case, the acceleration is:
a = (67-53.2) / 6
a = 2.3m / s2
We say that Kendall is accelerating at the rate of 2.3 m every second squared.
We conclude that the correct answer is the option: B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.
