Answer:
[tex]a=6\ m/s^2[/tex]
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,
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{20-2}{3}\\\\a=6\ m/s^2[/tex]
So, the acceleration of the cat is [tex]6\ m/s^2[/tex].
