Answer :
Let's carefully analyze the given statement:
1. The car starts with an initial velocity of 0 miles per hour.
2. After 3 seconds, the car's velocity reaches 60 miles per hour.
The question concerns the change in velocity over the specified time period.
When a car's velocity changes from an initial value to a final value within a certain time frame, the change in velocity is simply the difference between the final and initial velocities.
- Initial velocity ([tex]\(V_{initial}\)[/tex]) = 0 miles per hour
- Final velocity ([tex]\(V_{final}\)[/tex]) = 60 miles per hour
The change in velocity ([tex]\( \Delta V \)[/tex]) is calculated as follows:
[tex]\[ \Delta V = V_{final} - V_{initial} \][/tex]
Substituting the given values:
[tex]\[ \Delta V = 60 \text{ miles per hour} - 0 \text{ miles per hour} \][/tex]
[tex]\[ \Delta V = 60 \text{ miles per hour} \][/tex]
Therefore, the change in velocity is 60 miles per hour over a time period of 3 seconds.
The statement says, "If a car starts from 0 velocity and reaches 60 miles per hour in 3 seconds, the change in its velocity is 60 miles per hour in 3 seconds."
Given the calculations and analysis above, this statement is accurate.
Thus, the correct answer is:
A. True
