A tennis player hits a 0.1-kilogram tennis ball with her racket from the north end of a court. Her racket was traveling at 65 kilometers per hour. The ball accelerated at a rate of 20 meters per second squared. The ball hits the floor on the south end of the tennis court. The floor sends the ball toward the tennis players opponent with the same acceleration. How much force did the floor on the south end of the court exert on the ball?
A. 6.5 N
B. 1 N
C. 0.01 N
D. 7.5 N

To calculate the force exerted on the catcher's mitt by the ball, we can use the equation:

Force = mass × acceleration

Plugging in the given values:

Mass = 0.2 kg
Acceleration = 8 m/s^2

Force = 0.2 kg × 8 m/s^2
Force = 1.6 N

Therefore, the ball will hit the catcher's mitt with a force of 1.6 N. The correct answer is D.

To calculate the force exerted by the floor on the ball, we can use the equation:

Force = mass × acceleration

Plugging in the given values:

Mass = 0.1 kg
Acceleration = 20 m/s^2

Force = 0.1 kg × 20 m/s^2
Force = 2 N

Therefore, the floor on the south end of the court exerts a force of 2 N on the ball. The correct answer is not provided.

To calculate the force exerted by the floor on the ball, we can use the equation:

Force = mass × acceleration

Given values:
Mass = 0.1 kg
Acceleration = 10 m/s^2

Force = 0.1 kg × 10 m/s^2
Force = 1 N

Therefore, the floor on the south end of the court exerts a force of 1 N on the ball. The correct answer is B.

According to Newton's third law of motion, the reaction force exerted by the fence on the chair is equal in magnitude and opposite in direction to the force exerted by the chair on the fence.

Given that the force exerted by the chair on the fence is 8 N, the reaction force exerted by the fence on the chair is also 8 N.

Therefore, the correct answer is A. 8 N.
