Physics - W.E.P. Question with Solution | TestHub

A small block of mass 1 kg is placed at a distance 4 m from open end on a truck starting from rest with constant acceleration of $4\mathrm{m}/{\mathrm{s}}^2$, if ${\mu }_{\mathrm{s}}=0.3$ and ${\mu }_{\mathrm{k}}=0.2$ between truck & block. Find KE of block (in joule) w.r.t. truck when it is about to fall. $\left(\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right)$
