A wad of clay of mass m1 = 0.36 kg with an initial horizontal velocity v1 = 2.35 m/s hits and adheres to the massless rigid bar which supports the body of mass m2 = 1.37 kg, which can be assumed to be a particle. The pendulum assembly is freely pivoted at O and is initially stationary. The distance L = 1.36 m. Determine the angular velocity ω of the combined body just after impact. Why is linear momentum of the system not conserved?

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
