In Sl units, the position x of a spring-loaded electromagnetic valve varies over timet in the manner
described by the 2nd order ODE
* + ax +(B+ K)x = K
The term on the RHS is designed so that, if x is disturbed from its rest position, then it automatically
returns, ideally, after a short period of time with no overshoot.

the rest position of the system is x =
When a = 1, B= 1 and K =
4'
a) Suppose that this system is at rest for the period 0 < t < 3, but at t = 3 the system is disturbed.
Solve the ODE 'by hand' with initial conditions x(3)=
and x(3)= 2; and
