A 5 kg block with a speed of 3.0 m/s collides with a 10 kg block that has a speed of 2.0 m/s in the same direction. After the collision, the 10 kg block travels in the original direction with a speed of 2.5 m/s. (a) Draw (i) a before/after sketch, (ii) momentum & energy bar diagrams of the situation, and (iii) identify the collision as elastic, inelastic and completely inelastic. (b) what is the velocity of the 5.0 kg block immediately after the collison? (c) is there a change in total kinetic energy of the system because of the collision?
