To find the acceleration of the car, you can use the formula:
acceleration = (change in velocity) / time
Given that the initial velocity (u) is 24 km/hr, the final velocity (v) is 60 km/hr, and the time (t) is 10 seconds, we need to convert the velocities to meters per second (m/s) and the time to seconds (s) to ensure consistent units.
1 km/hr is equal to (1/3.6) m/s, so:
Initial velocity (u) = 24 km/hr = 24 * (1/3.6) m/s = 6.67 m/s Final velocity (v) = 60 km/hr = 60 * (1/3.6) m/s = 16.67 m/s Time (t) = 10 s
Now we can calculate the acceleration:
acceleration = (v - u) / t
acceleration = (16.67 m/s - 6.67 m/s) / 10 s acceleration = 10 m/s / 10 s acceleration = 1 m/s²
Therefore, the acceleration of the car is 1 m/s².
