Consider the following two$-$dimensional, incompressible flow through the converging channel as shown in Figure $1.$ Assume the cross$-$section area per unit depth is $A=\frac{1}{(1+0\mathrm{.}2s_L^T)}.,$ The mean velocity at $x=0$ is $V_1$

$($a$)$ Find the velocity $(5\%)$ and acceleration $(10\%$ of a particle moving along the centerline

$($b$)$ Find the position of a fluid particle $($at $x=0$ initially$)$ as a function of time. $(10\%$
