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 = mass × acceleration force = mass × acceleration force = weight × velocity force = weight × velocity force = mass × velocity force = mass × velocity force = weight × acceleration

9 answers

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

force = mass × acceleration

This equation is derived from Newton's second law of motion (F = ma), where force is equal to mass times acceleration.

A 0.2-kilogram softball is thrown toward a catcher’s mitt. The ball is accelerating at a rate of 8 meters per second squared. With what force will the ball hit the catcher’s mitt?(1 point)

To find the force with which the ball will hit the catcher’s mitt, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) times acceleration (a):

\[ F = m \times a \]

Given:

  • Mass (\(m\)) = 0.2 kg
  • Acceleration (\(a\)) = 8 m/s²

Now, plug in the values:

\[ F = 0.2 , \text{kg} \times 8 , \text{m/s}^2 = 1.6 , \text{N} \]

So, the force with which the ball will hit the catcher’s mitt is 1.6 N.

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 find the force exerted by the floor on the tennis ball after it hits the floor, we will use Newton's second law of motion (F = ma).

Given:

  • Mass of the tennis ball (\(m\)) = 0.1 kg
  • Acceleration of the ball (\(a\)) = 10 m/s²

Now, plug these values into the formula:

\[ F = m \times a \]

Calculating the force:

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

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

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)

8 N

According to Newton's third law of motion, for every action, there is an equal and opposite reaction. This means that if the wind exerts a force of 8 N on the lawn chair, the fence will exert an equal and opposite force back on the chair.

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