force = mass × acceleration
force = mass × acceleration

force = weight × velocity
force = weight × velocity

force = weight × acceleration
force = weight × acceleration

force = mass × velocity

7 answers

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

force = mass × acceleration

This relation is derived from 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.

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 calculate the force with which the ball will hit the catcher’s mitt, you can use Newton's second law of motion, which states:

\[ \text{Force} = \text{mass} \times \text{acceleration} \]

Given:

  • Mass of the softball = 0.2 kg
  • Acceleration = 8 m/s²

Now, calculate the force:

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

Therefore, 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 on the tennis ball by the floor, we can use Newton's second law of motion, which states:

\[ \text{Force} = \text{mass} \times \text{acceleration} \]

Given:

  • Mass of the tennis ball = 0.1 kg
  • Acceleration = 10 m/s²

Now, calculate the force:

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

Therefore, the force exerted by the floor on the tennis 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)

According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. This means that if the wind blows a lawn chair with a force of 8 N into a fence, 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
