The system shown in figure is initially at rest. Neglecting friction determine the force 'P' required if the velocity of the collar B is 5 m/s after 2 sec and corresponding tension in the cable.

Given :

u = o m/s

v = 5m/s

t = 2 sec

$ \text{Assumptions:}$

$\text{1) The total length of the string is $L$ meter.}$

$\text{2) $x_A $and $x_B$ are the displacements of block A and B respectively.} $

$\text{3) $K_1$, $K_2$ and $K_3$ be the constant length w.r.t block …
