Object A has of mass 7.20 kilograms, and object B has a mass of 5.75 kilograms. The two objects move along a straight line toward each other with velocities +2.00 meters/second and 1.30 meters/second respectively. What is the total kinetic energy of the objects after the collision, if the collision is perfectly elastic

Best ResponseYou've already chosen the best response.0that 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 ....

Best ResponseYou've already chosen the best response.1yes  Joules is the unit of energy if mass is in kg amd v in m/s then 0.5mv^2 is in joules

Best ResponseYou've already chosen the best response.1I 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

Best ResponseYou've already chosen the best response.050.8 was the right answer on the test question and i chose that one

Best ResponseYou've already chosen the best response.1yes  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

Best ResponseYou've already chosen the best response.1is 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
