Question

9.00 m/s (Cright) collides with 1.An object of mass 10.o kg moving with a velocity ofo another object of mass 20.0 kg moving at 6.00 m/ After the collision the 10.0 kg object continues to move sa direcei collides w What is the velocity of the 20.0 kg object after this collisio a velocityt s in the same s to move wi r this collision?
6. Show that the collision in questions 1 is elastic; that is find total KE before collision and total KE after collision. If they are equal, then collision is elastic.

Answer #1

During collision of objects, since there is no external force, the total linear momentum of the system remain conserved.

Further for elastic collision, the total kinetic energy also remain conserved. the solution is based on same principle as below:
