Calculating Average Force for a Baseball Batting Exercise

Click For Summary
SUMMARY

The discussion centers on calculating the average force exerted on a baseball during a batting exercise. The mass of the baseball is 145 grams, and it leaves the bat at a speed of 84 m/s after a contact time of 0.09 seconds. The correct formula for calculating net force is Fnet = mv/t, where mass must be converted to kilograms for the result to be in Newtons. The initial calculation of 135333.3 was incorrect due to the mass being in grams instead of kilograms.

PREREQUISITES
  • Understanding of Newton's Second Law of Motion
  • Familiarity with unit conversion (grams to kilograms)
  • Basic knowledge of kinematics
  • Ability to manipulate algebraic equations
NEXT STEPS
  • Learn about unit conversion for mass in physics
  • Study Newton's Second Law of Motion in detail
  • Explore kinematic equations related to force and motion
  • Practice problems involving average force calculations
USEFUL FOR

Students studying physics, coaches looking to understand the mechanics of baseball, and anyone interested in applying physics concepts to sports dynamics.

Physics average force need help!

Homework Statement



A coach is hitting pop flies to the outfielders. If the baseball (mass = 145 g) stays in contact with the bat for 0.09 s and leaves the bat with a speed of 84 m/s, what is the average force acting on the ball?

Homework Equations



Fnet=mv/ t

The Attempt at a Solution


Fnet= 145 x 84 / .09
I got 135333.3 and this wa incorrect. I think I am using the wrong equation... Please help!

Problem looks like units, assuming you were supposed to give your answer in Newtons. If you want the force in Newtons, you need the mass to be given in kg.
 
Thank you very much!
