ikr i dont understand
m1=7.20kg and m2=5.75kg v1=2m/s and v2=-1.3 that's all is given
that is prety long Q you have to find 1st V1' and V2' through their formulas then use the relation of K.E at start and in the end ....
If the collision is elastic then the KE after is equal to KE before KE = 0.5mv^2
my answers are in joules
yes - Joules is the unit of energy if mass is in kg amd v in m/s then 0.5mv^2 is in joules
you DO know the formula for Kinetic Energy?
I mean what is the answer .???
i have no clue
I have told you how to work out the answer Work out the KE of both masses before the collision it is the same total after the collision
yes I know I am asking that is there any short cut to solve it in minimum time that's what is iwant....
50.8 was the right answer on the test question and i chose that one
yes - the short cut to getting it in the minimum time is to do it yourself using the formula I gave you above. OR you can wait until someone breaks the code of conduct, and does you the DISSERVICE of posting the answer here
no I can do that thx...
is 50.8 the answer to ALL questions? It doesn't seem right to me for this one Taking someone's answer with no explanation is a dangerous thing here - MANY answers here are just plain wrong
idk but thats what the computer said
