Thanks krab i understand all of that.. but the one example that you didn't mention is the steal to steal stick. The equations indicate that steal to steal is just as lossy as clay to clay, that's the part that doesn’t seem right to me. I would expect clay to clay collision to be very lossy but...
Chi as specified in the original problem the two masses do stick hence the final velocity is fixed hence the loss of kinetic energy is fixed.
krab, the part i find unusual is that i would expect masses of two different types of material eg. clay to clay or steel to steel is to stick together...
Thanks for all your contributions.
By fixed i mean specified in the original problem.
In summary.. by all my calculations, because the final velocity is fixed because of the law of conservation of momentum the loss of kenotic energy is always constant in the example given without any...
Thanks for sticking with this one Pete.
I understand your replies that account for the loss of kinetic energy to thermal. But that doesn’t address the problem I’m having.
Let me try to explain.
In the original example the velocity and mass are fixed hence the total kinetic energy and...
Thanks for the reply Pete..
I should have made my description clearer..
What i mean here is if there is no loss of energy, that is KE, converted to thermal etc.. then there is a problem because if momentum is conserved then the final speed is determined irrespective of the nature or...
Thanks all for answering
i have no problem if some of the kinetic energy is lost during the collision but the out standing problem that i originally had still remains…
ie. It must be possible for 2 objects to collide and for the losses due to the collision to vary depending on the nature...
Hi ppl..
Can someone please explain the following problem to me?
Assuming a 3kg ball traveling at 4m/s hits and joins with a static 1kg ball (a perfect join with no loss of energy).
Momentum before collision = p = mv = 12kgm/s
Using conservation of momentum final velocity of total...
