Homework #12
1) A simple plan pendulum of mass m1 and length L is pivoted about point O. A mass m2 slides without friction along the massless rigid link of the pendulum and is connected to point O by a spring of stiffness k. The unstretched length of the
2D Rigid-body Linear and Angular Momentum
Linear momentum:
L = mv G
(section 15.2)
where m = total body mass
Note: momentum is a vector quantity
Angular momentum of the ith particle: H Pi = r m i v i (moment of linear momentum about P )
let r = x i + y j
