Block diagram of a unity positive feedback control loop: R(t) enters a summing junction, then gain block K/S, then plant (S-1)/((S-1)(S+2)), with output Y(t) fed back to the junction.

question:
find maximum velocity error constant(K_v)
feedback is :1 positive

the book says the right answer is:0.75

but every time i calculate E(s) it goes to the wrong answer!
please help!

Kv is K/2. The book's answer is correct if K = 1.5.
