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 10 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 player's opponent with the same acceleration. How much force did the floor on the south end of the court exert on the ball?(1 point)

To calculate the force with which the ball will hit the catcher's mitt, we can use the equation:

force = mass × acceleration

Given:
mass = 0.2 kg
acceleration = 8 m/s^2

Substituting the values into the equation:

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

Therefore, the force with which the ball will hit the catcher's mitt is 1.6 N.

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

force = mass × acceleration

Given:
mass = 0.1 kg
acceleration = 10 m/s^2

Substituting the values into the equation:

force = 0.1 kg × 10 m/s^2
force = 1 N

Therefore, the force exerted by the floor on the ball is 1 N.

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

Given:
Force exerted by the chair on the fence = 8 N

Therefore, the reaction force exerted by the fence on the chair will also be 8 N.
