Why are these algebraic expressions used and explain the logical error: Since a = b, then a2 = a * b Subtract b2 from both sides a2 – b2 = a * b – b2 Factor both sides: ( a + b )( a – b ) = b(a – b ) Divide both sides by ( a – b) ( a + b ) = b Since a...

Actually, just noticed that was for in x direction, so change sign on acceleration 35*sin(11)+(35)(1)=Fx 35*sin(11)+(35)(2)=Fx 
physics
this is kinda late answer, but still... 35*sin(11)Fx=0 This works for a = 0 35*sin(11)+maFx=0 More complete answer... (a!=0) So, for increasing rate of a = 1m/s^2 This is going in negative direction, so 35*sin(11)+(35)(1)=Fx And for a = 22/s^2 35*sin(11)+(35)(2)=Fx Crunch in...
