Physics
An observer is at point o. A car of mass m traveling at a constant velocity u is about to pass by her from the left as shown in the figure. Treating the car as a particle, determine the angular momentum of the car about the point o.
A pedestrian is in the middle of the road, standing still at point o. A bus of mass m is approaching him with a constant velocity u, as shown in the figure below. Considering the bus as a particle, find the angular momentum of it about the point o.
