Question

14) (Conservation of linear momentum) An air cart of mass m=1 kg and speed vo-Im's moves toward second identical air cart that is at rest. When the carts collide, they stick together and move as one a) Using the conservation of linear momentum, calculate the velocity ve when the carts stick together (this is also the velocity of the center of mass after collision). b) Calculate the kinetic energy before and after collision. Is the collision elastic Without any calculation, comment on the velocity of the center of mass of the two cars before and after collision. Veo ON

Answer 1

o Imi a . a 17.1= axu A luz 0.5 m/s] b) KEE LX1912= 0.51 KEJ = x 2 x 0-5²0-257 - inclactic c) It will remain unchanged as no external force is acting on the system.
