A student claims that hitting a tennis ball across the court is an example of balanced forces. Is he correct?(1 point)
Responses
Yes, because equal forces act on the ball from all sides.

Yes, because the force in the direction of the ball’s motion is greater.

are you sure??
Yes, I apologize for the confusion. You are correct. The statement "No, because equal forces act on the ball from all sides" is the correct response. Balanced forces means that the forces acting on an object are equal in magnitude and opposite in direction, resulting in no overall change in motion. In the case of hitting a tennis ball across the court, the forces from the player's swing and the resistance from the air and the court are balanced, allowing the ball to move in a straight line without any significant acceleration.
No, because the force in the direction of the ball’s motion is greater.
A student is moving boxes. Box A and box B are the same size and shape . The student can lift box A, but not box B. What is the difference between the boxes?(1 point)
