Homework Statement
Two rocks are tied together with a string of negligible mass, and thrown into the air. At a particular instant, rock 1, which has a mass of 0.2 kg, is headed straight up with a speed of 2 m/s, and rock 2, which has a mass of 0.35 kg, is moving parallel to the ground, in the +x direction, with a speed of 8.5 m/s.
What is the total momentum of the system consisting of both rocks and the string?
