To find the acceleration of the car, we can use the formula:
Acceleration (a) = (Final velocity - Initial velocity) / Time
Given: Initial velocity (u) = 24 km/hr Final velocity (v) = 60 km/hr Time (t) = 10 seconds
First, let's convert the velocities from km/hr to m/s to ensure consistent units:
Initial velocity (u) = 24 km/hr * (1000 m/1 km) * (1 hr/3600 s) ≈ 6.67 m/s Final velocity (v) = 60 km/hr * (1000 m/1 km) * (1 hr/3600 s) ≈ 16.67 m/s
Now we can calculate the acceleration:
Acceleration (a) = (16.67 m/s - 6.67 m/s) / 10 s Acceleration (a) = 10 m/s / 10 s Acceleration (a) = 1 m/s²
Therefore, the acceleration of the car is 1 m/s².
