    Answer:

    a=6\ m/s^2

    Explanation:

    Initial speed of a cat, u = 2m/s

    It takes the cat 3 s to reach a top speed of 20 m/s.

    We need to find the cat’s rate of acceleration during this time. Acceleration is equal to the rate of change of velocity. So,

    a=\dfrac{v-u}{t}\\\\a=\dfrac{20-2}{3}\\\\a=6\ m/s^2

    So, the acceleration of the cat is 6\ m/s^2.
