Two children run parallel to the x axis in opposite directions, as shown. Each child has a speed of 6 m/s and a mass of 50 kg. a) What is the total angular momentum (magnitude and direction) of both children about the point P halfway between them if each child is 4 m from the x axis? b) Is the direction into the page or out of the page? c) why is the magnitude not zero if they are going in the opposite directions?

A barbell spins around a pivot at its center at A. The barbell consists of two small balls, each with mass 450 grams (0.45 kg), at the ends of a very low mass rod of length d = 50 cm (0.5 m; the radius of rotation is 0.25 m). The barbell spins clockwise with angular speed 120 radians/s. We can calculate the angular momentum and kinetic energy of this object in two different ways, by treating the object as two...
