Question

Mech 14 Kinetic and internal enersy Initial Two identical carts on a frictionless track collide in three separate experiments. The initial conditions of each experiment ar t identical except that different bumper materials are applied to the carts. The outcome of each experiment is shown below C. Experiment I respectvey,.1. 2,and 3 be composed of the pair of carts in experiments the rinale three systems according to the fAnal Kineric energy. from largest to smallest. Ir 1, 2, and 3 et stivelytes of any systems 1, 2 respectively. 1. Rank the kinetic energy of any system is zero, state so explicitly. Explan. 2. Rank the three systems according to the absolute value of the change in kinetic energy, from largest to smallest. If the change in kinetic energy of any system is zero, state so explicitly. Explain. Collisions in which the kinetic energy of a system of colliding objects is constant are called elastic collisions. Collisio ns in which the kinetic energy decreases are called inelastic collisions 3. Which of the collisions, if any, are elastic? Which, if any, are inelastic? Explain.
