Beth is traveling east on a dirt road when she spots a pothole ahead. she slows her car from 14.0 m/s to 5.0 m/s in 6.0s. what is the cars acceleration

-1.5m/s^2

Explanation:

Initial velocity V1 = 14.0 m/s

Final velocity V2 = 5.0 m/s

Time taken = 6.0s

The car's acceleration = ?

Since acceleration is the rate of change of velocity per unit time

i.e acceleration = (V2 - V1) / T

Acc = (5.0 m/s - 14.0 m/s) / 6.0 s

Acc = (-9.0m/s) / 6.0s

Acc = -1.5m/s^2 ( the negative acceleration means the car is slowing down)

Thus, the cars acceleration is -1.5m/s^2

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow
