SUMMARY

The discussion centers on calculating the required increase in speed of a baseball bat (object B) to compensate for a decrease in its mass while maintaining the same impact result when striking a baseball (object A). Specifically, it examines a scenario where a 28oz bat swung at 140mph is compared to a 24oz bat, with the goal of determining the necessary speed increase to achieve equivalent performance. The reference to Robert Adair's "Physics of Baseball" suggests that established physics principles can be applied to solve this problem effectively.

PREREQUISITES
  • Understanding of basic physics concepts such as mass, speed, and momentum.
  • Familiarity with the principles of conservation of momentum.
  • Knowledge of the physics of baseball, particularly the impact dynamics between bat and ball.
  • Ability to perform calculations involving ratios and proportions in physics contexts.
NEXT STEPS
  • Study the conservation of momentum in elastic collisions.
  • Learn about the physics of baseball, focusing on bat-ball impact dynamics.
  • Explore Robert Adair's "Physics of Baseball" for in-depth analysis and formulas.
  • Research the effects of bat mass and speed on hitting performance in baseball.
USEFUL FOR

This discussion is beneficial for physics students, baseball coaches, sports scientists, and anyone interested in the mechanics of baseball performance and impact calculations.

ok, I'v never been on a physics site before but thought I'd look for one for help on this question... also forgive me but I probably won't be using proper physics terms... object A at a constant mass & speed is struck by object B which has a mass 5x that of object A and a speed 2x that of A. the result I can measure, my question is something like this, on paper how can I calculate what increase in speed of B will be required to overcome a decreese in mass of B? now applied to the real world... 70mph fast ball (5oz) 28oz bat swung at 140mph (end of bat) how much faster do you need the bat to travel with a 24oz bat to achieve the same result assuming all other variables remain the same. thanks Abe

A good place to find out a little more about formulating your question would be Robert Adair's Physics of Baseball. Large libraries should have it.
