Unformatted text preview: Problem Set 7: Problem 5. Problem: A particle of mass 2 m translating at speed U approaches two vertically aligned pairs of particles connected by rods of negligible mass. The four particles connected by the rods all have mass m and the bars have length 2 r . After the particles collide, the incident particle continues moving horizontally, while the two pairs of particles translate horizontally and rotate at angular velocity as shown. The collision is perfectly elastic. (a) What is the velocity of the center of mass of the five particles after the collision? (b) Determine the angular velocity as a function of U and r .
