The acceleration of the car can be calculated using the formula:
Acceleration (a) = (Final velocity (v_f) - Initial velocity (v_i)) / Time (t)
In this case, the initial velocity (v_i) is 5 m/s, the final velocity (v_f) is 25 m/s, and the time (t) is 10 seconds. Plugging these values into the formula, we get:
Acceleration (a) = (25 m/s - 5 m/s) / 10 s = 20 m/s / 10 s = 2 m/s²
Therefore, the acceleration of the car is 2 m/s².
