Finding Acceleration Given Distance and Final Speed

Click For Summary
SUMMARY

The discussion focuses on calculating the average acceleration of a baseball thrown by a pitcher, who accelerates the ball over a distance of 3.5 meters before release. The initial speed is 0 m/s, and the final speed at release is 41 m/s. To find the average acceleration, the formula used is derived from the kinematic equation: \( a = \frac{{v^2 - u^2}}{{2s}} \), where \( v \) is the final velocity, \( u \) is the initial velocity, and \( s \) is the distance. Applying these values yields an average acceleration of 246.14 m/s².

PREREQUISITES
  • Understanding of kinematic equations
  • Familiarity with basic physics concepts such as velocity and acceleration
  • Ability to manipulate algebraic formulas
  • Knowledge of metric units (meters, seconds)
NEXT STEPS
  • Study the kinematic equation for uniformly accelerated motion
  • Learn about the implications of constant acceleration in physics
  • Explore real-world applications of acceleration calculations in sports
  • Investigate how to derive other kinematic equations from basic principles
USEFUL FOR

This discussion is beneficial for physics students, sports scientists, and anyone interested in the mechanics of motion, particularly in the context of sports performance analysis.

1. A pitcher uses 3.5m to accelerate a baseball before release. Find the average acceleration of a ball starting at zero m/s and traveling 41m/s at release

Thanks in advance. I'm lost with what I need to do.

Hi aprymek! Welcome to PF! :smile:

Assume a constant acceleration …

you know the initital and final speed, and the distance, so which formula should you use? :wink:
