Consider the mechanical system shown. Assume that $u$ is the force applied to the cart and is the

input to the system. The displacement $x$ is measured from the equilibrium position and is the

output of the system. Obtain:

$1-(2$ pts$)$ The transfer function $x\frac{s}{U}(s)$ of the system.

$2-(1$ pt$)$ The final value when the force $u$ is a step input of magnitude $3.$
