a A 3 kg mass is launched at 45 degrees above the horizontal at 5 m/s as part of an engineering contest. To be sure your report stands out, you decide that in addition to the traditional translational projectile calculations, you will apply concepts of angular momentum. What is the initial angular momentum around the launch point? 11.2.6b When the mass is at the apex of its trajectory, what is the magnitude of the angular momentum around the launch point in kg m/s? Enter answer here 12. 2.6c What is the angular momentum around the launch point just before the mass hits the ground in kg m/s? Enter answer here 1 point 1 point
