Ek = (m·V²)/2
V - velocity of system after the collision
m = m1 + m2
Ek = (m1 + m2)·V²/2
Ek = (200 +250)·2,3²/2 = 450·5,29/2 = 1190,25 J
hope this helps :3
I am involved with a community garden and an interactionist might like to study our organization. We have some very knowledgeable people like ex soil scientist's to guide us and we believe in thoro ugh discussion of our plans for work in the garden and encourage everyone to participate and our work is very co-operative and we love what we are doing because it is for the benefit of all of us plus the wider community who can grow vegetables in our garden.
