Answer:

Explanation:
Acceleration is the rate of velocity's change with time.
We can calculate it by dividing the change in velocity over time.

Let's define the variables. The final velocity is 15 meters per second. The initial velocity is 5 meters per second. The time is 5 seconds.

Substitute the values into the formula.

Solve the numerator first.

Divide.

The acceleration of the bus is <u>2 meters per second squared.</u>
