Dynamics impact problems
WebDec 3, 2013 · Group dynamics can lead otherwise sensible individuals to make (or agree to) decisions they might not come to on their own. At times the effects are positive, as when some group members help others overcome prejudices. But the dynamics of a group often have negative consequences. Since nearly every company relies on collective decision … Web•In most impact problems, the initial velocities of the particles and the coefficient of restitution, e, are known, with the final velocities to be determined. •For oblique impact …
