What object moving at 30 ms takes 5 s to come to a stop what is the objects acceleration?

The acceleration of the object can be calculated using the formula:

acceleration = (final velocity - initial velocity) / time

Given that the final velocity is 0 m/s (since the object comes to a stop), the initial velocity is 30 m/s, and the time is 5 s, the acceleration can be found by plugging these values into the formula.
