A block of metal weighing $\displaystyle 2$ kg is resting on a frictionless plane (as shown in figure). It is struck by a jet releasing water at a rate of $\displaystyle 1 \mathrm{kgs}^{-1}$ and at a speed of $\displaystyle 10 \mathrm{~ms}^{-1}$. Then, the initial acceleration of the block, in $\displaystyle \mathrm{ms}^{-2}$, will be :
Official answer
(3)
$\displaystyle 5$
