Jeff and Zak have worked out a stunt-show performance involving hovercrafts on a collision course. Just before the collision, Jeff and Zak will safely leap out of the hovercrafts, but they still have a little physics to work out. The two hovercrafts, each with a mass of 925 kg, are hovering at a constant height above the ground and are traveling toward each other as shown in the figure. The first hovercraft is traveling at v1 = 14.0 m/s to the right, and the second is traveling at v2 = 23.0 m/s to the left. (Let the positive x direction point to the right.) V1 V2 (a) If the hovercrafts undergo a completely inelastic collision, what is their final velocity after the collision? (Enter your answer to at least one decimal. Express your answer in vector form.) Vf = m/s (b) How much kinetic energy is lost in the collision?
