Najiba is running at 5 meters per second and decelerates uniformly to 2 meters per second in 2 seconds. a. What was Najiba’s rate of acceleration?
To find Najiba's rate of acceleration, we can use the formula:
Acceleration = (final velocity - initial velocity) / time
Acceleration = (2 m/s - 5 m/s) / 2 s
Acceleration = -3 m/s / 2 s
Acceleration = -1.5 m/s²
Therefore, Najiba's rate of acceleration was -1.5 meters per second squared.
