Two carts mounted on an air track are moving toward one another. Cart 1 has a speed of 1.1 m/s and a mass of 0.4? kg. Cart 2 has a mass of 0.58 kg. (a) If the total momentum of the system is to be zero, what is the initial speed [in mls} of Cart 2? [Enter a number.) : m (h) Does it follow that the kinetic energy of the system is also zero since the momentum of the system is zero? 0 Yes 0 No (c) Determine the system's kinetic energy [in J} in order to substantiate your answer to part (b). [Enter a number.) :1
