While playing her soccer game, Samantha runs down the field at 10 meters per second. She has a constant speed and does not change direction. What is Samantha's acceleration? (1 point)
• The acceleration is 10 m/s^2 because her velocity did not change.
• The acceleration is 0 m/s^2 because her velocity did not change.
• The acceleration is 10 m/s^2 because her velocity increased.
• The acceleration is 0 m/s^2 because her velocity increased.
The correct answer is:
• The acceleration is 0 m/s^2 because her velocity did not change.
The correct answer is:
• The acceleration is 0 m/s^2 because her velocity did not change.
To determine Samantha's acceleration, we need to understand that acceleration is the rate of change of velocity. In this scenario, it is stated that Samantha runs down the field at a constant speed of 10 meters per second without changing direction.
Since her velocity remains the same, there is no change in velocity over time. Therefore, her acceleration is 0 m/s^2 because there is no acceleration if there is no change in velocity.
Therefore, the correct answer is:
• The acceleration is 0 m/s^2 because her velocity did not change.
