A bus changes its velocity from 5 m/s to 15 m/s in 5 seconds. What is its acceleration?
sladkih [1.3K]

Answer:

\boxed {\boxed {\sf A. \ 2 \ m/s^2}}

Explanation:

Acceleration is the rate of velocity's change with time.

We can calculate it by dividing the change in velocity over time.

a=\frac{v_f-v_i}{t}

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.

v_f= 15 \ m/s \\v_i= 5 \ m/s \\t= 5 \ s

Substitute the values into the formula.

a=\frac{15 \ m/s- 5 \ m/s}{5 \ s }

Solve the numerator first.

  • 15 m/s - 5 m/s= 10 m/s

a=\frac{10 \ m/s}{5 \ s}

Divide.

a= 2 \ m/s/s = 2 \ m/s^2

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