Answer:
[tex]\boxed {\boxed {\sf A. \ 2 \ m/s^2}}[/tex]
Explanation:
Acceleration is the rate of velocity's change with time.
We can calculate it by dividing the change in velocity over time.
[tex]a=\frac{v_f-v_i}{t}[/tex]
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.
[tex]v_f= 15 \ m/s \\v_i= 5 \ m/s \\t= 5 \ s[/tex]
Substitute the values into the formula.
[tex]a=\frac{15 \ m/s- 5 \ m/s}{5 \ s }[/tex]
Solve the numerator first.
[tex]a=\frac{10 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= 2 \ m/s/s = 2 \ m/s^2[/tex]
The acceleration of the bus is 2 meters per second squared.
