Average Kinetic Energy of 2 Objects
If I had 2 objects of equal mass ( 10kg for example ), and knew that the average speed of the 2 objects was 8 ms-1 , is it possible to calculate the average kinetic energy of the 2 objects. I attempted the speed of object 1 to be 6 ms-1 and the speed of Object 2 to be 10 ms-1 . So the average kinetic energy would be (180 + 500)/2 = 340 Joules , however that is not equal to 320 when you use the average speed so 1/2 * 10 * 82. I understand about root mean squared, but if you don't know the initial values of the speed but only the average is it just not possible to calculate average kinetic energy?
