The acceleration of an object can be calculated using the formula:
Acceleration (a) = (Change in velocity) / (Change in time)
Given that the initial velocity (u) is 5 m/s, the final velocity (v) is 25 m/s, and the time taken (t) is 10 seconds, we can substitute these values into the formula:
a = (v - u) / t
a = (25 m/s - 5 m/s) / 10 s
a = 20 m/s / 10 s
a = 2 m/s²
Therefore, the acceleration of the car is 2 m/s².
