Making Momentum Chart and Finding Force for Baseball and Bat

Click For Summary

Homework Help Overview

The discussion revolves around a collision problem involving a bat and a baseball, focusing on momentum and force calculations. Participants are tasked with creating a momentum chart and determining the average force exerted on the bat during the collision.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants discuss the initial and final momentum of both the bat and the baseball, questioning how to represent these vectors accurately. There is an inquiry about the initial velocity of the bat, which is not provided, and how it can be derived from the given data.

Discussion Status

The conversation is ongoing, with participants exploring different aspects of the problem. Some have offered insights into the momentum vectors, while others are seeking clarification on the initial conditions necessary for solving the problem.

Contextual Notes

There is a noted absence of the bat's initial velocity, which is crucial for completing the momentum calculations. Participants are also navigating the boundaries of homework guidelines, indicating a focus on understanding rather than providing direct solutions.

A 1 kg bat hits a 150 g baseball traveling at 40 m/s opposite to the bat’s direction. This collision lasts 1/1000 of a second. Immediately after it is hit the baseball has a velocity of 50 m/s opposite to its initial direction and the bat 10 m/s in the same direction as the as it moved initially. Draw a momentum chart for the collision and find the average force on the bat.

Sounds like homework so may get moved to that section.

Have you tried to solve it yourself?

Its study prep for a quiz I have. I am assuming the initial momentum for both will be a vector of the same length, just in an opposite direction for each one. And then final momentum for the baseball is a vector in the other direction just a little bit longer, and for the baseball its a same direction vector but a lot shorter. Is this correct?

The initial velocity of the bat isn't given. I believe you will have to calculate it from the data before and after the impact.
