A thin rod of mass m and length l rests on a frictionless table and is struck at a point l/4 from its center of mass by a clay ball of mass m moving at speed v.
A thin rod of mass m and length l rests on a frictionless table and is struck at a point l/4 from its center of mass by a clay ball of mass m moving at speed v. The ball sticks to the rod. If the rod is free to pivot about a frictionless pin at its center, find the angular velocity of the rod after the collision. Also find the velocity of the point at the top of the rod...

long thin rod length h A particle, with mass m, is moving through space with constant velocity v, as shown in the diagram. COM It eventually collides with and sticks to the end of a long thin uniform rod, which has mass M and length /h and is initially at rest. The mass of the particle (m) is negligible compared with the mass of the rod. (a) Show the angular momentum of the particle about the COM of the rod...

A uniform rod of mass m and length L = 2 meters is suspended from one end by a frictionless pivot so that it can swing freely in the plane of the paper, as shown on the right. When the rod is at rest it is struck by a clay ball of equal mass m with initial velocity v_0 = 10 m/s at an angle of 60 degree with the vertical rod. The clay ball strikes the rod at the...

1. A thin rod of mass M and length d hangs vertically from a frictionless pivot attached to one end. A piece of clay of mass m moving horizontally at a speed v hits the rod a distance x from the pivot and sticks to it. Discussion Questions: (In the first 5-10 min a random group will be selected to explain.) • What “type” of collision is happening? What is and is not conserved? • Consider the analogous linear momentum...

A uniform rod with a mass m and length L has one end attached to a pivot. The rod swings around on a frictionless horizontal table with angular speed wo. A ball with mass m (so same mass as the rod) is placed on the table a distance d from the pivot. The ball is made of clay so when the rod strikes it, the ball sticks to the rod (i.e., inelastic collision). If the final (post-collision) angular velocity of...

A rod of mass "10m" and length "L" is hanging through a pivot at one end. A lump of clay of mass "m" is thrown perpendicular to the rod hitting it at the opposite end of the pivot. The lump sticks to the rod causing the rod to swing m a vertical circle up to an angle of 90 degree. Given [m L], Determine: The initial speed of the lump of clay The angular speed of the system just after...
