Two air track carts move forward one another on an air track cart 1 has a mass of 0.45kg and a speed of 1.1m/s. Cart 2 has amass of 0.65kg.
a) What speed should cart 2 have if the total momentum of the system is to be zero?
b) Since the momentum of the system is zero, does it follow that the kinetic energy of the system is also zero?
c) Verify your answer to part (b) with calculating the system kinetic energy.
