In the figure(Figure 1) a 1.5 kg block is held at rest against a spring with a force constant k = 720 N/m . Initially, the spring is compressed a distance d. When the block is released, it slides across a surface that is frictionless except for a rough patch of width 5.0 cm that has a coefficient of kinetic friction μk = 0.45. Part A Find d such that the block's speed after crossing the rough patch is 2.4...
A block with mass m = 16 kg rests on a frictionless table and is accelerated by a spring with spring constant k = 5072 N/m after being compressed a distance x1 = 0.568 m from the spring’s unstretched length. The floor is frictionless except for a rough patch a distance d = 2.8 m long. For this rough path, the coefficient of friction is μk = 0.48. 1) How much work is done by the spring as it accelerates...
