Problem 3. A mass m and a mass 3m are each initially at rest. They are both subjected to a constant force F that lasts for a time At the

end of that time t: (a) Which mass has the larger linear momentum or are they the same? If one is larger, determine the factor by which it is larger.(b) Which mass has the larger kinetic energy or are they the same? If one is larger, determine the factor by which it is larger.
