Step 1

Part g:

The part can be solved in two ways:

• Apply final value theorem and find the ultimate value of the response. First find the Laplace transform of the input function u(t)=5sin2t and then put the final value theorem and the limits s tends to 0 in the function.
• Find the response or output in terms of t by using inverse transform of Y(s) function and then put the value to t to infinite.

We are using method (1) in order to find the value of output at t tends to infinite.

The Laplace transform of the input function is

Step 2

Hence the response is

Step 3

According to the final value the...
