SUMMARY
The average force applied by a 0.140-kg baseball traveling at 45.0 m/s on a catcher's glove, which recoils backward 11.0 cm, is calculated using the equation F=ma. The acceleration was determined using the formula vf^2=vi^2-2ad, resulting in an acceleration of 9205 m/s². Consequently, the average force calculated is 1,289 N, which is consistent with the high deceleration required to stop the baseball in such a short distance.
PREREQUISITES
- Understanding of Newton's Second Law (F=ma)
