Q: A ( 1kg ) ball of clay moving with a velocity ( vbi ) collides and sticks to the end of a ( 120cm ) rod of uniform mass ( 2kg ). Assuming that the ball and rod are at rest upon a frictionless surface: ( a ) Where is the new center ofContinue reading “ENERGY AND MOMENTUM: Conservation of Linear and Angular Momentum ( Part 1 )”

Q: Consider a system in which a mass ( m1 = 6kg ) moves in the +x-direction at ( 2 m/s ) as a mass ( m2 = 2kg ) moves in the -x-direction at ( – 4 m/s ): How may we use the center of mass ( c.o.m. ) of this system toContinue reading “ENERGY AND MOMENTUM: Elastic Collisions and the Center of Mass Velocity ( Part 3 )”
ENERGY AND MOMENTUM: Elastic Collisions and the Center of Mass Velocity ( Part 2 )
In Part 1 of this entry, it was determined that the center of mass between objects moving with constant velocities is also constant ( vcm ): We will now use mass ( kg ) and instantaneous-distance coordinates along ( x ) to determine the system’s center of mass. Let’s begin using the x-coordinates of (Continue reading “ENERGY AND MOMENTUM: Elastic Collisions and the Center of Mass Velocity ( Part 2 )”
ENERGY AND MOMENTUM: Elastic Collisions and the Center of Mass Velocity ( Part 1 )
A system’s center of mass is the location where the average mass distribution of the system is located. Consider a system in which two equal masses rest at the ends of a balance: The sum of torques acting upon the system is zero, and it will remain in static equilibrium until acted upon by anContinue reading “ENERGY AND MOMENTUM: Elastic Collisions and the Center of Mass Velocity ( Part 1 ) “
