answer all part's please

(8%) Problem 8: Penny is adjusting the position of a stand up piano of mass mp = 190 kg in her living room. The piano is lp = 1.6 m in length. The piano is currently at an angle of Op = 54 degrees to the wall. Penny wants to rotate the piano across the carpeted floor so that it is flat up against the OP wall. To move the piano, Penny pushes on it at the point furthest from the wall. This piano does not have wheels, so you can assume that the friction between the piano and the rug acts at the center of mass of the piano. Randomized Variables mp = 190 kg 4 = 1.6 m Op = 54 degrees Forbes, David - david.forbes @doane.edu F Otheexpertta.com @theexpertta.com - tracking id: 9N69-72-B9-45-AB7A-35264.
