A 17.8 kg flood light in a park is supported at the end of a horizontal beam of negligible mass that is hinged to a pole. A cable connected to the beam helps to support the light. (In thefigure,

In Figure, a stationary block explodes into two pieces and R that slide across a frictionless floor and then into regions with friction, where they stop. Piece L, with a mass of 2.6 kg, encounters a coefficient of kinetic friction
Three objects are connected on the table as shown in Figure . The table is rough and has a coefficient of kinetic friction of .350. The objects have masses of 4.00 kg, 1 kg, and 2.00 kg, as shown, and the pulleys are frictionless. a) Determine The acceleration of each object and their directions. b) Determine The tensions in the two cords.
Replace the Cartesian equation with equivalent polar equations.
