For my problem the (1-cos45) is .48

Ok I have figured out that the .2 is from 1-cos but I still keep getting the wrong answer! Could you solve it so I can see what you did?

Solution Attempt: Ok so for A: ω1=((1/3)(2.8)(1.52))/ ((1/3)(2.8)(1.52))+m(1.12)√3(9.81m/s2)/1.5= (4.429kg/s)/(2.1kg)+1.21m ½(4.429kg/s)2/(2.1kg)+1.21m I don't know what to do now. Where did they get the .2 from in their example?
