A block with m1 - 8 kg, is placed on a sled with my = 2 kg. Block m, suddenly acquired an initial velocity of 2.5 m/s parallel to the horizonal surface pointing to the right. There is friction between block and the sled and the sled is sitting on a frictionless surface. The block bounced back and forth between the two ends of the sled a couple of rounds and eventually stopped moving with respect to the sled. How much kinetic energy of the system is loss during the whole process? m1= 8kg V =2.5m/s m2=2kg O 11J O 15 J O 10 J 0 3 J 0 5J
