Kesson 4 Assignment (Chapter 13.1-13.4)
Equation of Motion for a System of Particles
Learning Goal:
Consider the mass and pulley system shown. Mass m_(1)=32kg and mass m_(2)=14kg. The angle of the inclined plane is given, and the coefficient of kinetic friction between mass m_(2) and the inclined plane is mu _(k)=0.12. Assume the pulleys are massless and frictionless. ( Eigure 1)
