6) Kaya is riding her dirt bike eastward on a dirt road. She spots a pothole ahead. Kaya slows her car from 14.0 m/s to 5.5 m/s in 6.0 s. What is her acceleration?

The acceleration of Kaya is .

Explanation:

Given that,

Initial speed of Kaya, u = 14 m/s

Final speed of Kaya, v = 5.5 m/s

Time, t = 6 s

We need to find Kaya's acceleration. We know that it is given by the change in speed per unit time. Its formula is given by :

So, the acceleration of Kaya is . Hence, this is the required solution.
