Physics - NLM Question with Solution | TestHub

The 40 kg block is moving to the right with a speed of $1.5\mathrm{m}/\mathrm{s}$ when it is acted upon by the forces ${\mathrm{F}}_1$ and${\mathrm{F}}_2$. These forces vary in the manner shown in the graph. Find the velocity of the block after $\mathrm{t}=6\mathrm{s}$. Neglect friction and mass of the pulleys and cords.
