Unformatted text preview: T = 1 2 M tot R 2 + 1 2 r 2 , with the reduced mass given by: 1 = 1 m 1 + 1 m 2 The motion within and outside the centre of mass can be separated: L outside = outside ; L inside = inside p = m v m ; F ext = m a m ; F 12 = u 1.5.2 Collisions With collisions, where B are the coordinates of the collision and C an arbitrary other position, holds: p = m v m is constant, and T = 1 2 m v 2 m is constant. The changes in the relative velocities can be derived from: S = p = ( v aft v before ) . Further holds L C = CB S , p S = constant and L w.r.t. B is constant....
