Answer:

The acceleration of the object is
$4\ m/s^2$ and it is negative acceleration.

Explanation:

We are given with, an object is moving east, and its velocity changes from 65 m/s to 25 m/s in 10 second.

The rate at which velocity of an object is changing is called its acceleration.

Initial speed is 65 m/s and final speed is 25 m/s.

It is given by :

$a=((25-65)\ m/s)/(10\ s)\\\\a=-4\ m/s^2$

So, the acceleration of the object is
$4\ m/s^2$ and it is negative acceleration.
