....I got zero problem with Pnchy trying to explain the different aspects of impact dynamics.
This is derailing the thread.
If 16 years old could understand then why hasn't this issue been resolved long ago? From above it is obvious there are some concept you don't understand.Grandpa said:However, don't be misled. The guy who started this thread is posing as if he has information, but the knowledge and calculations he has presented so far are the kind of thing that a 16 year old school physics student with a poor grasp of the material would say
Yes, engineers must be precise and what people think happens is irrelevant. What actually happens is what we should strive to know.izra said:"i find the main reason for so many disagreements between pnachtway and everyone else is that he takes everything

USDC, you post is off topic and adds nothing to the debate.
Back on topic.
Lets assume the rubber is somewhat linear. The ball at rest depresses the rubber a little when the there is only the force due to gravity. Lets say 0.01mm. When the ball is accelerated at 9.807m/s^2 and the force between the rubber and ball doubles the amount the ball sinks into the rubber doubles to 0.02mm So how far does the ball depress the rubber if I accelerate the paddle upwards at only 1/2 g? This should be simple.
