... Example : Two boxes and a pulley. Two boxes are connected by a cord running over a pulley. The coefficient of kinetic friction between box A and the table is 0.20. We ignore the mass of the cord and pulley and any friction in the pulley, which means we can assume that a force applied to one end of ...

introduction and basic concepts
... The unit kilogram (kg) is the mass unit in the SI system, and it is sometimes called kg-mass, whereas kgforce (kgf) is a force unit. One kg-force is the force required to accelerate a 1-kg mass by 9.807 m/s2. In other words, the weight of 1-kg mass at sea level on earth is 1 kg-force. Discussion dim ...

... A block of mass m is given an initial velocity by the spring. The spring has a spring constant k, and is squeezed 0.200 m when the block is at A. Between A and B the slope has friction coefficients :s = 0.75 and :k = 0.65. After point B the system is frictionless. The block goes around the circular ...
