1. (for submission) Consider two particles of mass m and m2 connected by a massless rod. The first particle is rotating in a circle a height h above the xy-plane and the second in a circle a distance h below the xy-plane. Let us parametrize their motion as r1 = r cos(wt)ex + r sin(wt)ey + hez, 12 = -r cos(wt)ersin(wt)e, -hez. where r is assumed constant. (a) Compute the angular momentum of this system. (b) Compute the torque required to keep this system rotating at constant w.
