2) A block of mass m = 1 is sitting on a table and is attached to a spring of strength k = 5 so that it can slide horizontally on the table. If the coefficient of friction between the block and the table is b=4 and an external force of F(t) 10 sin(t) acts on it, then the position of the block, x(t), satisfies "+4x+5x 10 sin(t). = Find the general solution to this differential equation.
