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)

Answer 1

To find the force exerted by the floor on the ball, we need to use Newton's second law of motion, which states that force (F) equals mass (m) times acceleration (a).

Given that the mass of the tennis ball is 0.1 kg and the acceleration is 10 m/s^2, we can calculate the force as:

F = m * a
F = 0.1 kg * 10 m/s^2
F = 1 N

Therefore, the correct answer is:

1 N

Answer 2

To calculate the force exerted by the floor on the ball, we can use Newton's second law of motion, which states that force is equal to mass multiplied by acceleration (F = m*a).

Given:
Mass of the tennis ball (m) = 0.1 kilograms
Acceleration (a) = 10 meters per second squared

Using the formula F = m*a, we can calculate the force:
F = (0.1 kg) * (10 m/s^2) = 1 N

Therefore, the floor on the south end of the court exerted a force of 1 N on the ball.

Answer 3

To find the force exerted by the floor on the south end of the tennis court on the ball, we can use Newton's second law of motion, which states that force is equal to mass times acceleration.

First, let's find the acceleration of the ball. We are given that the ball accelerated at a rate of 10 meters per second squared. Since the acceleration is the same both when the ball is hit by the racket and when it hits the floor, the acceleration remains constant.

Next, let's find the mass of the ball. We are given that the mass of the ball is 0.1 kilograms.

Using Newton's second law, we can calculate the force exerted by the floor on the ball using the formula:

Force = mass * acceleration

Force = 0.1 kg * 10 m/s^2

Force = 1 N

Therefore, the floor on the south end of the court exerted a force of 1 Newton on the ball. So the correct answer is 1 N.
