1. Convert Units:

* Initial Velocity (u): 18 km/h = 18 * (1000 m / 3600 s) = 5 m/s

* Final Velocity (v): 36 km/h = 36 * (1000 m / 3600 s) = 10 m/s

2. Calculate Acceleration:

* Acceleration (a): Use the formula: a = (v - u) / t

* a = (10 m/s - 5 m/s) / 5 s

* a = 1 m/s²

3. Calculate Distance:

* Distance (s): Use the formula: s = ut + (1/2)at²

* s = (5 m/s * 5 s) + (1/2 * 1 m/s² * (5 s)²)

* s = 25 m + 12.5 m

* s = 37.5 m

Therefore, the car covers a distance of 37.5 meters in 5 seconds.
