To find the acceleration of the car, we can use the following formula:
Acceleration = (Change in Velocity) / Time
First, let's convert the velocities from km/hr to m/s, since the SI unit for acceleration is meters per second squared (m/s²).
Initial velocity (u) = 36 km/hr = (36 * 1000) / 3600 m/s = 10 m/s Final velocity (v) = 54 km/hr = (54 * 1000) / 3600 m/s = 15 m/s
Using the formula:
Acceleration = (15 m/s - 10 m/s) / 10 seconds
Calculating the result:
Acceleration = 0.5 m/s²
Therefore, the acceleration of the car is 0.5 m/s².
