Unformatted text preview: against the outside edge (2m from the middle), providing a constant frictional force of 30N. At what rate does the angular momentum decrease? You are riding your bicycle through campus. Which way does the angular momentum vector of your tires point? A 5,000kg plane is flying 200m/s at a constant altitude of 8,000m. What is the angular momentum of the plane about you when you see the plane from the quad at Houghton College. The system below is released from rest. What is the direction of the net torque on the pulley? 20kg 10kg You are riding your bicycle down Rt. 19. You suddenly jerk your handle bar to the left. What does this cause the tire to do?...
