A dog is sleeping under a tree when it see a squirrel run by. The dog runs 3.5m/s in 15s to chase the squirrel. What's was it's average rate of acceleration?

Given :

The dog runs 3.5 m/s in 15 s to chase the squirrel.

To Find :

The average rate of acceleration.

Solution :

Initial velocity, u = 0 m/s .

Final velocity, v = 3.5 m/s .

Time taken, t = 15 s.

We know, average acceleration is given by :

Therefore, average acceleration is 023 m/s².

Hence, this is the required solution.
