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) Responses The acceleration is 0 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 did not change. The acceleration is 10 m/s^2 because her velocity did not change. The acceleration is 0 m/s^2 because her velocity increased. The acceleration is 0 m/s^2 because her velocity increased. The acceleration is 10 m/s^2 because her velocity increased.

14 of 2314 of 23 Items Question Two forces act on an object. One force has a magnitude of 10 N directed north, and the other force has a magnitude of 2 N directed south. What is the net force on the object?(1 point) Responses 8 N north 8 N north 12 N south 12 N south 8 N south 8 N south 25 N north 25 N north Skip to navigation
The net force on the object can be found by subtracting the southward force from the northward force.

10 N (north) - 2 N (south) = 8 N (north)

Therefore, the net force on the object is 8 N north.
15 of 2315 of 23 Items Question An object at rest remains at rest. An object in motion remains in motion unless acted upon by an outside force. This describes which of Newton’s Laws of Motion?(1 point) Responses First and Third Laws of Motion First and Third Laws of Motion Second Law of Motion Second Law of Motion First Law of Motion First Law of Motion Second and Third Laws of Motion Second and Third Laws of Motion Skip to navigation
The correct answer is: First Law of Motion.

The statement "An object at rest remains at rest. An object in motion remains in motion unless acted upon by an outside force." describes Newton's First Law of Motion, also known as the law of inertia.
Suppose 25 children who weigh the same are playing a game of tug-of-war. Five children pull with 10 newtons of force, while ten children pull with 15 newtons of force in the opposite direction. How can one determine the net force on the rope?(1 point) Responses The newtons are in the same direction, so the newtons can be multiplied. The newtons are in the same direction, so the newtons can be multiplied. The forces are in opposite directions, so the newtons can be divided. The forces are in opposite directions, so the newtons can be divided. The forces are in the same direction, so the newtons can be added. The forces are in the same direction, so the newtons can be added. The forces are in opposite directions, so the newtons can be subtracted.
The correct answer is: The forces are in opposite directions, so the newtons can be subtracted.

To determine the net force on the rope, you need to consider the forces applied in opposite directions. In this case, five children pull with 10 newtons of force in one direction, and ten children pull with 15 newtons of force in the opposite direction.

By subtracting the force exerted in one direction from the force exerted in the opposite direction, you can find the net force.

15 N - 10 N = 5 N

Therefore, the net force on the rope is 5 newtons in the direction of the larger force.
The graph above shows an object’s motion. Which statement is true? (1 point) Responses The object starts at rest and then accelerates at a constant rate. The object starts at rest and then accelerates at a constant rate. The object does not move. The object does not move. The object accelerates at an increasing rate followed by a decreasing rate. The object accelerates at an increasing rate followed by a decreasing rate. The object accelerates at an increasing rate.
Since the graph is not provided in the question, it is impossible to determine which statement is true about the object's motion. Please provide the graph for further analysis.
To measure average speed, what data is required?(1 point) Responses The distance traveled and the time spent The distance traveled and the time spent The direction of travel and the weight of the bike The direction of travel and the weight of the bike The direction and the distance of travel The direction and the distance of travel The weight of the bike and the time spent
The correct answer is: The distance traveled and the time spent.

To measure average speed, you need to know the distance traveled and the time spent. Average speed is calculated by dividing the total distance traveled by the total time taken.
The graphs below depict different cars moving on a straight road. Which graph shows a car that is not in motion? (1 point) Responses A A B B C C D D
Since the graphs are not provided in the question, it is impossible to determine which graph shows a car that is not in motion. Please provide the graphs for further analysis.
Which example shows an object acted on by two balanced forces?(1 point) Responses A baseball rolling to a stop A baseball rolling to a stop A car moving at a constant speed in a constant direction A car moving at a constant speed in a constant direction A snowflake landing on a roof A snowflake landing on a roof A skateboard rolling down a hill with increasing speed
The correct response is: A car moving at a constant speed in a constant direction.

When an object is acted upon by two balanced forces, it means that the forces are equal in magnitude and opposite in direction, causing the object to maintain a constant speed in a constant direction.
