Answer :
Final answer:
Accelerations are calculated as the rate of change of velocity. The car in the question is decelerating at a rate of 600 km/h^2.
Explanation:
In physics, acceleration is defined as the rate of change of velocity per unit of time. It is calculated as the change in velocity divided by the time taken for that change. In this case, the initial velocity of the car is 60 km/h and the final velocity is 0 km/h. The time taken for this change is 0.1 hours.
Therefore, the acceleration would be calculated as: (final velocity - initial velocity) / time = (0 km/h - 60 km/h) / 0.1 hours. This calculates to -600 km/h^2. The negative sign indicates deceleration or slowing down. So, the rate at which the car is accelerating (or, in this case, decelerating) is -600 km/h^2. Hence, the correct answer is B) 600 km/h^2.
