Answer:
[tex]\boxed {\boxed {\sf 4\ m/s^2}}[/tex]
Explanation:
Acceleration is the rate of change of an object with respect to time. It is the change in velocity over the time.
[tex]a= \frac{v_f-v_i}{t}[/tex]
The car starts at 10 meters per second and increases to 20 meters per second in 2.5 seconds.
Substitute the values into the formula.
[tex]a= \frac{ 20 \ m/s - 10 \ m/s}{2.5 \ s }[/tex]
Solve the numerator.
[tex]a= \frac{10 \ m/s}{2.5 \ s}[/tex]
Divide.
[tex]a= 4 \ m/s/s[/tex]
[tex]a= 4\ m/s^2[/tex]
The acceleration of the car is 4 meters per second squared.
