The two ropes seen in Figure Ex11.9 are used to lower a 235 kg piano 5.5 m from a second-story window to the ground. How much work is done by each of the three forces? (T1 = 1820 N andT2 = 1110 N)
t1 is 45degrees north of east
t2 is 60degrees north of west
w = J
T1 = J
T2 = J
w=fd
I got work done by weight to be 12666.5j which is correct, how do i find the tensions?
