What Is the Average Force Exerted by the Bat on the Baseball?

In summary, the problem involves calculating the magnitude of the average force exerted by a bat on a baseball that is pitched at 40 m/s and hit back at 60 m/s. Using the equation Favg = delta p/ delta t, the attempt at a solution found a value of 3 for delta p, but the correct answer is 3000N due to an incorrect sign in one of the velocity values.

Homework Statement


A 150-g baseball pitched at a speed of 40 m/s is hit straight back to the pitches at a speed of 60 m/s. If the bat is in contact with the baseball for 5 ms calculate the magnitude of the average force exerted by the bat on the baseball.


Homework Equations


Favg = delta p/ delta t


The Attempt at a Solution


delta p = m (Vf-Vi) = 0.150(60-40) = 3
Favg = 3/0.005 = 3

however the answer is 3000N, can anyone clarify where I made the mistake?

One of the values you have put in for the velocities is not correct. Remember that you have to account for the direction of the ball with the appropriate sign.

oh thanks for pointing that out, it should be 60-(-40)
 

FAQ: What Is the Average Force Exerted by the Bat on the Baseball?

1. What is linear momentum in baseball?

Linear momentum in baseball refers to the quantity of motion possessed by a baseball pitcher as they throw the ball. It is a vector quantity that is determined by the mass and velocity of the pitcher and the ball.

2. How is linear momentum related to the speed of a baseball pitch?

The speed of a baseball pitch is directly related to the linear momentum of the pitcher and the ball. The greater the linear momentum, the faster the pitch will be.

3. How does a pitcher increase their linear momentum?

A pitcher can increase their linear momentum by increasing their mass or their velocity. This can be achieved through proper technique, strength training, and conditioning.

4. What is the role of linear momentum in the physics of a baseball pitch?

Linear momentum plays a crucial role in the physics of a baseball pitch. It is the quantity of motion that is transferred from the pitcher to the ball, resulting in the ball's movement and speed towards the batter.

5. How does air resistance affect the linear momentum of a baseball pitch?

Air resistance can decrease the linear momentum of a baseball pitch by slowing down the speed of the ball. This is why pitchers often use specific techniques, such as throwing a curveball, to decrease the impact of air resistance on the pitch.
