A painter of mass 50.0 kg stands on a platform of mass 60.0 kg and pulls on two ropes which hang over pulleys, as shown. He pulls each rope with a force of 800.0 N. Assuming a coordinate system where +y is up, calculate the y-component of the acceleration ay. ay can either be positive or negative depending on the direction of the acceleration.

A 70 kg painter is painting the wall of a building. He stands on a horizontal board of length 4.5 m and mass 15 kg, suspended from vertical ropes attached to each end. If the painter stands 1.9 m from one end of the board, what would the tensions in the ropes be? tension in rope nearer to the painter tension in rope further from the painter

A 2400-kg airplane pulls two gliders, the first of mass 330 kg and the second of mass 280 kg, down the runway with an acceleration of 1.3 m/s2 (Figure 1). Neglect the mass of the two ropes and any frictional forces. Part A: Determine the magnitude of horizontal thrust of the plane's propeller. Part B: Determine the magnitude of the tension force in the first rope. Part C: Determine the magnitude of the tension force in the second rope. Part...

A person with mass mp = 74 kg stands on a spinning
platform disk with a radius of R = 2.37 m and mass md =
184 kg. The disk is initially spinning at ? = 1.9 rad/s. The person
then walks 2/3 of the way toward the center of the disk (ending
0.79 m from the center).
