Hi there,
I need your help to prove the following, please:
Ek0-Ek1>0
Thanks in advance. (:

May11 said:Did you get my question? need a further explanation?
May11 said:It is a plastic collision, masses exert forces on each other, ending up with a joint velocity (U). We fisrt have to express the equation of the velocity at the end of the collision, that is : U= Mv/M+m
Then, express the equation of Ek0 and Ek1 :
Ek0= Mv²/2
Ek1= (m+M)u²/2 = M²v²/2(m+M)
Then, prove that Ek0-Ek1>0 ...that is pretty much all! we are not given any further...
May11 said:Umm, makes sense. The teacher said we have to use more formulas which are not given in the question, haven't expressed them, to branch out a little from what we are given. I will ask if your proof is valid and acceptable.
Thanks a heap! :)
The term "Prove Ek0-Ek1>0" is a mathematical statement that means to show or demonstrate that the difference between two values, denoted as Ek0 and Ek1, is greater than zero. This is typically done using mathematical proofs and logical reasoning.
Proving Ek0-Ek1>0 is important because it allows us to establish a relationship between two values and determine the direction of change. It is commonly used in scientific research and data analysis to support hypotheses and draw conclusions.
There are several common methods for proving Ek0-Ek1>0, including algebraic manipulations, graphical representation, and mathematical induction. Depending on the specific context, other methods such as calculus or statistics may also be used.
Sure, here's an example: Let Ek0 = 5 and Ek1 = 3. We want to prove that Ek0-Ek1>0. Using algebra, we can rewrite this as 5-3>0, which simplifies to 2>0. This is a true statement, so we have successfully proven that Ek0-Ek1>0 for these specific values.
Yes, proving Ek0-Ek1>0 is not limited to mathematics and can also be applied in other fields such as physics, chemistry, and economics. In these fields, it is often used to analyze data, make predictions, and support theories or laws.
