Impulse and Momentum for Systems of Particles - Example Problem 10.1-3

 

Consider a dumbbell consisting of two 2-kg spheres rigidly connected by a 3-m bar of negligible mass. The dumbbell slides across a smooth table. If the center of mass of the system is translating with velocity v_G = 4i m/s and the system is rotating with angular velocity ω = 1k rad/sec, determine a) the linear momentum of the system and b) the angular momentum of the system with respect to O for the instant shown in the figure.

 

 

Given:

• m = 2 kg
• L = 3 m
• v_G = 4i m/s
• ω = 1k rad/s

 

Find:

• G
• H_O

 

Calculate the linear momentum of the system.

 

G = i kg-m/s
