    2. Slower object: KE = 0.5m*V^2.
    Faster object: KE = 0.5m*(2V)^2 =
    0.5m*4*V^2.

    0.5m*4V^2/0.5m*V^2 = 4 Times.

    3. KE = 0.5m*V^2

    9. MA = 20/100

    10. W = F*d. d = 0.

    stop talking stuff and help one another! :( I am so disappointed in you kids! You're parents will be mad when I tell on all of you. I am a teacher/tutor here and I will not tolerate this behavior!

    I don't know who you are, but the next time you try to impersonate a teacher, start your sentences with a capital letter and use great punctuation skills. Secondly, I have no idea how you were not only going to impersonate me without using correct spelling and improper punctuation, but you also expect these kids to believe you can contact their parents with no information about their personal life, stop using scare tactics on these poor kids.

    This is just pure madness, you guys don't fight! let's just agree to disagree. Honestly, in my opinion, I believe the it doesn't matter if you cheat or not, if you learned something then you have achieved something:) but still you should at least try because if you don't you won't. meaning, if you believe you can't, you won't try to be anything other than what you can be!
