Question

A block B is pulled by of 18N applied to a
light pulley as shown in the figure. If the
coefficient of friction is 0.4 and the
acceleration of the block is 0.5ms-2,

Answer 1

$\star\:\:\:\bf\large\underline\blue{Answer:—}$

2T = F = 18 N

F = 9 N

$\boxed{\bf{\red{Formula:—T-μmg=ma}}}$

9 - 0.4 × mg = 0.5 m

9 = 4.5 m

m = 2 kg
