SUMMARY

The discussion focuses on calculating angular momentum during a collision between a ball and a bat. The ball, with a mass of 0.16 kg, travels at 54 m/s before being struck by the bat, reversing its direction to 40 m/s. The moment of inertia of the bat is 0.30 kg, and the collision occurs 0.8 m from the pivot point. The bat continues to swing with a velocity of 0.35 times its angular velocity (ω) after the collision, indicating that both linear and angular momentum are conserved during the event.

PREREQUISITES
  • Understanding of angular momentum conservation principles
  • Knowledge of linear momentum and its conservation
  • Familiarity with moment of inertia calculations
  • Basic physics concepts related to collisions
NEXT STEPS
  • Study the principles of conservation of angular momentum in collisions
  • Learn how to calculate moment of inertia for various shapes
  • Explore the relationship between linear and angular velocity
  • Practice problems involving collisions and momentum conservation
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and collision dynamics, as well as educators seeking to explain angular momentum concepts in practical scenarios.

Homework Statement



Pivots.jpg


I need to find ω. The values I have are:

Ball of mass .16 KG is traveling horizontally at 54 ms^-1 and its struck by the bat. The ball still travels horizontally but in the opposite direct at speed 40ms^-1. The moment of inertia is 0.30kg about the pivot and hits the ball at a point that is 0.8m away from the pivot. After the collision the bat is still swinging in the same position but with a velocity of 0.35 ω

Homework Equations

The Attempt at a Solution



Really unsure how to do this ... this test is due in an hours time and I am really struggling with this one. Any guidance would help no end!

(a bit late, but …)

in any collision, both ordinary momentum and angular momentum are conserved …

in this case, you would use conservation of angular momentum :wink:
