4. A soccer ball is traveling downfield with a force of 1.2 kN and strikes another soccer ball that is stationary. Which of the following describes the result of the collision?(1 point)
Neither ball will move after impact.
The stationary soccer ball will begin moving upfield and the ball that struck it will slow down.
The stationary soccer ball will begin moving downfield and the ball that struck it will slow down.
The stationary soccer ball will begin moving downfield and the ball that struck it will accelerate.
No ones got the answers ?!!
1. The statement that is true about the situation is: It describes displacement, which is a vector quantity. To explain, displacement is a vector quantity because it involves both the magnitude (7 miles) and the direction (to the west) of the sailboat's position relative to the pier.
2. The situation in which the use of a vector quantity would be most appropriate is determining the net force that is acting on an object. A vector quantity, in this case, is necessary to consider both the magnitude and direction of the different forces acting on the object to determine the overall net force.
3. The statement that best describes force is: Force is a vector quantity that measures both direction and magnitude of a push or pull on an object. This is because force involves both the direction and magnitude of the push or pull, which makes it a vector quantity.
4. The result of the collision between the soccer balls would be: The stationary soccer ball will begin moving downfield and the ball that struck it will slow down. This is due to the principle of conservation of momentum, where the momentum from the incoming ball is transferred to the stationary ball. As a result, the stationary ball gains momentum and starts moving, while the incoming ball loses momentum and slows down.
1. The statement that is true about this situation is: It describes displacement, which is a vector quantity.
2. The situation in which the use of a vector quantity would be most appropriate is: determining the net force that is acting on an object.
3. The statement that best describes force is: Force is a vector quantity that measures both direction and magnitude of a push or pull on an object.
4. The result of the collision between the two soccer balls is: The stationary soccer ball will begin moving downfield and the ball that struck it will slow down.
