Hello there!

I think you should stay. is full of answers, if you need some answers just ask a question and wait. You can ask me some questions if need help. I might not be on a lot but you can trust me to give you the answers you need. I mostly do social studies and math.

I hope I changed your mine, I am probably so late anyways. Have a great day!

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
