Thank you :) I just thought they were both looking at the change in velocity and in both equations there is a way to account for the differences in mass (before and after collision) so I didn't think was absurd to wonder if there is a connection between the formulas.
In an inelastic collision is the change in kinetic energy equal to the difference of final and initial momentum if one of the objects is initially at rest? For example:
m1v = (m1+m2)Vf -----> 0 = (m1+m2)Vf - m1v1
1/2(m1+m2)Vf^2 - 1/2m1v^2 = (m1+m2)Vf - m1v1
Or totally wrong? Thanks!
Sorry I thought numbers that didn't have the variable being derived weren't present in the derivation. The reason why you add "+c" to the end of integrations? And since cos(10π*0.6) = 0, whether the rest of the equation was there wouldn't matter since you're multiplying by 0. Anyways thank you :)
Ahh forgot the negative. v=35*10π*-sin(10πt) thank you! For acceleration would you just take the derivative of that for a = 35*10π*10π* -cos(10πt) ? Or since in v=35*10π*-sin(10πt) the sine function equaled zero and the rest didn't really matter was is supposed to be v=10π*-sin(10πt) in which...
I haven't taken calc in three years and my physics book doesn't exactly go over chain rule, that's why I came here for help.
Would you derive with respect to t? v=35*10π*sin(10πt) ?
