Question

Two carts mounted on an air track are moving toward one another. Cart 1 has a speed of 0.8 m/s and a mass of 0.53 kg. Cart 2 has a mass of 0.71 kg. (a) If the total momentum of the system is to be zero, what is the initial speed of Cart 2 in meters per second? m/s (b) Does It follow that the kinetic energy of the system is also zero since the momentum of the system is zero? Yes No (c) Determine the system's kinetic energy in joules in order to substantiate your answer to part (b).
