A 3.50kN piano is lifted by 3 workers at a constant speed to an apartment 25.0m above the street, using a pulley system fastened to the roof of the building. Each worker can deliver 165 W of power, and the pulley system is 75% efficient. Neglecting the mass of the pulley and ropes, find the time for the workers to lift the piano from the street to the apartment window.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
