Answer:
m/s²
Explanation:
As per the provided information in the given question, we have :
- Initial velocity (u) = 60 km/h
- Final velocity (v) = 0 (As it stops)
- Time taken (t) = 10 seconds
We are asked to calculate its acceleration.
In order to calculate its acceleration, firstly we need to convert initial velocity in its standard form, that it m/s.
- 1 km/h = 5/18 m/s
_______________________
Now, by using the acceleration formula:
- v denotes final velocity
- u denotes initial velocity
- a denotes acceleration
- t denotes time
∴ Acceleration of the car is m/s².

More Information:
- Acceleration is the rate of change in velocity.
- Its SI unit is m/s².
- It is a vector quantity.
- Negative acceleration is called retardation.
- Retardation is also called deceleration.
