I had a discussion last night that I was not sure how to develop fully. There are some species of Turltes which live for 255 years and some that live substantially less, The sturgeon fish http://en.wikipedia.org/wiki/Sturgeon" live extremely long outlasting tons of other fish, some...
"An elastic collision is defined as one in which both conservation of momentum and conservation of kinetic energy are observed. This implies that there is no dissipative force acting during the collision and that all of the kinetic energy of the objects before the collision is still in the form...
Hello,
A very basic question, with a bit of confusion.
a ball hitting a wall which is not moving with velocity v in an elastic collision has its momentum conserved, opposite velocity; -v.
if the ball is to collide with a wall which has a velocity -v, equal speed towards the ball, what is...
