Fill table 3(a). 5- Repeat all the above for inelastic collision and record your data in Table 3 (b) V;- V 2i Table 3(a) m=1kg and my=2kg m1 Elastic Vector VIsi V zxi Pixi P 2x Pixr P zxr Px P; Ki (m/s (m/s (m/s (m/s) (m/s) (kgm's) (kgm/s) (kgm/'s) (kgm/s) (kgm/s) (kgm's) (J) Vector V z Vzyr Plyi P zy Ply P zy P.
