SUMMARY

The discussion centers on the mechanics of a spinning ball that bounces forward after being dropped from a height of 0.835m with an initial angular velocity of 76 rad/s. Upon bouncing, the ball exhibits a vertical velocity of 3.1m/s and a forward horizontal velocity of 1.838m/s, attributed to the effects of friction and conservation of angular momentum. The relationship between the loss of angular momentum and the gained horizontal velocity is established through the radius of the ball. This highlights the interplay between angular and linear motion in the context of bouncing dynamics.

PREREQUISITES
  • Understanding of angular momentum and its conservation principles
  • Basic knowledge of kinematics, specifically vertical and horizontal motion
  • Familiarity with the effects of friction on moving objects
  • Concept of angular velocity and its impact on linear velocity
NEXT STEPS
  • Study the principles of conservation of angular momentum in detail
  • Explore the relationship between friction and motion in bouncing objects
  • Investigate the mathematical modeling of angular velocity and its effects on linear motion
  • Learn about the physics of collisions and energy transfer during bounces
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in the dynamics of motion and the principles governing the behavior of spinning objects during collisions.

The ball is given no initial horizontal velocity. It is however given an initial angular velocity of 76 rad/s and allowed to drop vertically from a height of 0.835m. Right after the ball bounces its vertical velocity is 3.1m/s upwards and its forward horizontal velocity is 1.838m/s and the ball reduced spin. My question is what gives the ball its horizontal velocity? Furthermore would it be possible to relate the loss in angular momentum (due to reduced speed) to the horizontal velocity gained?

Friction

Yes, via the radius.
 
Hello Ron, :welcome:

Please post homework in the homework forum and fill in the template. You post looks very weird, starting with "The ball" ... what ball ?

But I give you compimenets for answering your own question ! Or at least searching in the right direction: conservation of angular momentum.
