Question 131
Two particles, each of mass m and speed v, move in opposite directions along parallel lines separated by distance d. What is the magnitude of the total angular momentum about a point midway between the lines?
Question 132
Why is the angular momentum of a particle moving in the x-y plane directed along the z-axis?
Question 133
If a particle moves only in the x-y plane, which component of its angular momentum is non-zero?
Question 134
What are the components of the angular momentum l of a particle?
Question 135
