Acat accelerates from rest to 10m/s when it sees a dog. this takes 2 seconds. what was the acceleration of the cat

Answer :

Acceleration of the cat is

Explanation:

It is given that,  

Initial speed of the cat, u =0 (at rest)

Final speed of the cat, v = 10

Time taken, t = 2 s

Let a is the acceleration of the car. We know that the rate of change of velocity of an object is called its acceleration. Mathematically, it is given by :

So, the acceleration of the cat was . Hence, this is the required solution.
