complete the following 3 steps. 1. Indicate what your chosen system is (which objects are included in the system?) as well as your initial and final instants. Explain how your choice will help you solve the problem. 2. Draw a momentum-impulse bar chart for your chosen system that is consistent with the information given. 3. Write an equation using the bar chart as a guide and solve for any unknowns. A 6-kg bowling ball moving at 3 m/s hits a single 2-kg pin, knocking it forward at 6 m/s.
