Awad of clay of mass m1 with an initial horizontal velocity v1 hits and adheres to the massless rigid bar which supports the body of mass m2, which can be assumed to be a particle. the pendulum assembly is freely pivoted at o and is initially stationary. determine the angular velocity ˙ of the combined body just after impact. why is linear momentum of the system not conserved?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
