Question

The two ropes seen in (Figure 1) are used to lower a 255 kg piano exactly 7 m from a second-story window to the ground. Figure 1 shows the piano with 3 vectors of force applied to it. The vertical vector w of 2500 newtons is directed downward. Vector T1 of 1830 newtons is directed along one rope upward and to the left 60 degrees above the horizontal. Vector T2 of 1295 newtons is directed along the other rope upward and to the right 45 degrees above the horizontal. The figure shows the piano with 3 vectors of force applied to it. The vertical vector w of 2500 newtons is directed downward. Vector T1 of 1830 newtons is directed along one rope upward and to the left 60 degrees above the horizontal. Vector T2 of 1295 newtons is directed along the other rope upward and to the right 45 degrees above the horizontal. Part A: How much work is done by w? Express your answer in joules. W = J
