Hi, please show full solutions and also explain how you get the answers in physics terms so it's understandable. The correct final answers are written beside too. This is one whole question to be answered. I can't post it separately since it's related. Thank you. 12. A stationary 6.0 kg object blows apart into 3 pieces.

9y Is. Part 9 of 10 - Analyze Now Jed and Kadia tackle a homework problem: An object of mass m, = 13 kg and velocity v, = 5.5 m/s crashes into another object of mass m, = 6 kg and velocity v2 = -20.5 m/s. The two particles stick together as a result of the collision. Because no external forces are acting, the collision does not change the total momentum of the system of two particles, so the principle of conservation of linear momentum applies. m,V1 + m2v2i = (m, + m2)vf %3D If Jed and Kadia use the one-dimensional conservation of momentum equation to find the final velocity of the two joined objects after the collision, what do they obtain? (Indicate the direction with the sign of your answer.) -2.71 -2.71 m/s Part 10 of 10 - Analyze Although the forces that the two objects exert on each other cannot change their total momentum, they can change the total kinetic energy in an inelastic collision such as the one being considered.
