Thank you very much :D
Thanx I will try it out
Solved it thank you
I know how to speak Arabic, but I don't get your question , if you rephrase it , I may understand what you mean ;)
Thanks the answer was right, I related it to the small mass and it made sense ,, I submitted it , and it was right
No I didn't get it right :S ,, I did it like this exactly ( 0.0095 + 1.45 ) sqrt ( 2*9.8*0.124) = 0.0095 vi
I got my mistake ,, thank you very much for the help :)
Thanx ,, but I got something equals to 239.51 m/s .. and I don't think it is right .. I did it like this 1/2 ( 0.0095 + 1.45 ) sqrt ( 2*9.8*0.124) = 0.0095 vi
I know that ,, but I don't think the will give this kind of stupid question to a first year college student. I only know that it is a center of mass equation !
