I need to make animation showing two balls colliding with each other. The animation can be onli in one dimension + time. It have to look like this 1. O-----------><------------O 2. ------------->OO<----------- 3. O<--------- -------->O m1*v1+m2*v2 = m1*v3+m2*v4 & m1*(v1^2)/2 + m2*(v2^2)/2 = m1*(v3^2)/2 + m2*(v4^2)/2 where: m1,m2 - mass of balls v1,v3 - velocity of 1st ball before and after collision v2,v4 - velocity of 2nd ball before and after collision I worked out: v3=(2*m2*v2+(m1-m2)*v1)/m1+m2 v4=((v1 - v2)(m1+m2)+2*m2*v2+(m1-m2)*v1)/m1+m2 time (I'm not sure about that) t1 - before collision; t2 - after; t -complete time[0..99] position of balls before collision - r1,r2 position of balls after collision - r3,4 r0 - initial position r1=r0+(v1*t1) r2=r0-(v2*t2) r3=? r4=? and I do not know how to transmit it to Mathematica. I don't have this program in home, I can only use it in school so my time of useing it is limited & I can't experiment with it.Should I use Animate commend or any other?
