the chart shows the time, initial velocity, and final velocity of three riders.

which best describes the riders?

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.

Answer

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

Explanation

Acceleration is the rate of change of velocity. It is calculated as follows;

a = (v - u)/t

Where a⇒ acceleration

v ⇒ final velocity

u ⇒ initial velocity

t ⇒ time taken.

For Gabriella;

a = (32-55)/10 = -23/10 = -2.3

Since acceleration is negative, Gabriella was desecration (slowing down.

For Franklin,

a = (50-50)/8.5 = 0

This means no acceleration.

For Kendall;

a = (67-53.2)/6 = 13.8/6 = 2.3

Positive acceleration means, he was speeding up.

From the choices the correct answer is B. Gabriella is slowing down at the same rate that Kendall is speeding up, and Franklin is not accelerating.
