1. (Target C?) TWo carts are constrained to roll along a straight track. The carts are equipped with rubber bumpers. Cart A has a mass m and is initially traveling to the right at speed on. Cart B has a mass 4m and is initially traveling to the right at speed (1f3)v{1. After the carts collide, cart B is traveling to the right at speed (3/5)v- What is the velocity of cart A after the collision? Your result will be in terms of no. 2. (Target C3) A sh jumps out of the water. A cat, who was standing nearby, jumps, catches the sh in midair, and lands in a boat that happened to be passing by at the right time. The sh has a mass of 3kg and the cat has a mam of 5kg. At the time the sh is caught by the cat, the sh has a velocity {3'1 = 0-25: + 23} mfs and the cat has a velocity :72 = 1.55: mfs What is the velocity of the cat and sh the instant after the cat catches the sh
