Q. A barbell spins around a pivot at its center at A. The barbell consists of two small balls, each with mass 400 grams (0.4 kg), at ends of a very low mass rod of length d = .6 m. The barbell spins clockwise with angular speed 20 radians/s.
Consider the two balls separately, and calculate Ltrans 1,A and Ltrans 2,A (both direction and magnitude in each case).
