Question

A block of mass $1.5kg$ placed on a rough horizontal surface is pulled by a constant horizontal force of $1.2kg-f$. The coefficient of friction between the block and the surface is $0.3$. Find the acceleration produced in terms of $g$

Answer 1

Consider,

Force applied $=F$

Friction force $=f$

$F-f=ma$

$1.2g-\left(0.3\right)\left(1.5\right)g=1.5a$

Therefore, $a=0.5g$

Hence, the acceleration produce $0.5g$
