What Is the Acceleration of a Baseball Hit by a Bat?

Click For Summary
SUMMARY

The discussion focuses on calculating the acceleration of a baseball hit by a bat, transitioning from an initial velocity of 41 m/s south to a final velocity of 47 m/s north. The contact time between the bat and the ball is 1.9 milliseconds. The correct formula to use is V2 = V1 + a(delta t), where the velocities must be assigned proper directional signs. The acceleration can be determined by rearranging the equation to solve for 'a'.

PREREQUISITES
  • Understanding of kinematic equations, specifically V2 = V1 + a(delta t)
  • Knowledge of vector components and directional signs in physics
  • Familiarity with units of measurement, particularly meters per second (m/s) and milliseconds (ms)
  • Basic algebra skills for rearranging equations
NEXT STEPS
  • Review vector addition and subtraction in physics
  • Study the concept of constant acceleration and its implications
  • Learn about the effects of contact time on momentum changes
  • Explore real-world applications of kinematic equations in sports physics
USEFUL FOR

Students studying physics, particularly those focusing on kinematics, as well as educators and anyone interested in the dynamics of sports equipment interactions.

Homework Statement



A baseball traveling horizontally at 41m/s is hit by a baseball bat, causing its velocity to become 47 m/s [N]. The ball is in contact with the bat for 1.9 ms, and undergoes constant acceleration during this interval. What is that acceleration?

Homework Equations



V2 = v1 + a(delta t)

The Attempt at a Solution


41= 47 + (a)(0.0019) ?? is this right?

V1 and V2 look interchanged. You need to consider the proper signs on them as well.
