The discussion revolves around calculating impact velocity using the coefficient of restitution (CoR) based on the heights from which a ball is dropped and bounces. Participants are exploring the relationship between energy conservation and the CoR in the context of impact dynamics.
The discussion is active, with various interpretations being explored regarding the role of the CoR and the application of energy conservation principles. Some participants have offered guidance on using mass as a variable, while others challenge the initial question's premise.
Participants note the lack of explicit information regarding the mass of the ball and the implications of energy loss during the bounce, which may affect the calculations involved.
Use m for the mass of the ball.bionut said:Yes, I thought of that... but don't know the mass of the ball?
bionut said:Hi all, I know this may see basic but how would I go about calcualting Impact velovity?
The only information I have is:
Height dropped, height bounced and from here I can calculate the CofR...
But how would I go about finding impact velocity
Some mechanical energy is lost in the bounce. Thus there is a coefficient of restitution.hms.tech said:I don't get the question, i think it is wrong just because there is no need for the Coefficient of Restitution to find the impact (final ) velocity .
The Equations for constant acceleration , once applied would be used to find the Impact velocity AND the rebound velocity
