A baseball collides with a baseball glove. Which equation is used to calculate the force the glove exerts on the ball during the collision?(1 point) Responses force = weight × acceleration force = weight × acceleration force = weight × velocity force = weight × velocity force = mass × acceleration force = mass × acceleration force = mass × velocity

Answer 1

The correct equation to calculate the force the glove exerts on the ball during the collision is:

force = mass × acceleration.

This is based on Newton's second law of motion, which states that the force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Answer 2

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) Responses 6.5 N 6.5 N 7.5 N 7.5 N 0.01 N 0.01 N 1 N

Answer 3

To calculate the force that the floor on the south end of the court exerted on the tennis ball, you can use Newton's second law of motion, which states:

\[ F = m \cdot a \]

Where:

• \( F \) is the force,
• \( m \) is the mass of the ball, and
• \( a \) is the acceleration.

Given:

• Mass \( m = 0.1 \) kg (100 grams),
• Acceleration \( a = 10 \) m/s².

Now, plug these values into the equation:

\[ F = 0.1 , \text{kg} \times 10 , \text{m/s}² \] \[ F = 1 , \text{N} \]

Thus, the force that the floor exerted on the ball is 1 N.

Answer 4

The wind blows a lawn chair that weighs 4 kg into a fence with a force of 8 N. How much reaction force does the fence exert on the chair?(1 point) Responses 2 N 2 N 0.5 N 0.5 N 8 N 8 N 0 N

Answer 5

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that the force exerted by the wind on the lawn chair will be matched by the force exerted by the fence on the chair.

Given that the wind blows the lawn chair into the fence with a force of 8 N, the fence will exert an equal and opposite force of 8 N on the chair.

Thus, the reaction force that the fence exerts on the chair is 8 N.
