Question

A pulley with three blocks are shown in figure. Find acceleration and tension of each block.

Answer 1

Net acceleration of the system is,

$a=\frac{60-40}{10}$

$a=2m{s}^2$

All block will move with acceleration $2m{s}^2$ for $T_1$ and $T_2$.

$T_1-40=4\times 2,30-T_2=6$

$T_1=48N,T_2=24N$
