Needs work. 100kmph is not a velocity. Deceleration is not sudden. There is no such thing as the "speed" of deceleration. 10 kmph is not a deceleration. And if it were, we would need to know HOW LONG it decelerated. Otherwise an engaging and intriguing question.

The object travels approximately 138.8 meters while decelerating from 100 km/h at a rate of 10 km/h. This calculation involves converting units and using kinematic equations to find the distance based on the time taken to stop. By calculating the time to stop and applying it to the distance formula, we arrive at the final result.
