Momentum=23.4kgm/sVelocity=2m/s

$\\ \rm\longmapsto Momentum=Mass\times velocity$

$\\ \rm\longmapsto Mass=\dfrac{Momentum}{Velocity}$

$\\ \rm\longmapsto Mass=\dfrac{23.4}{2}$

$\\ \rm\longmapsto Mass=11.7kg$

Explanation:

From crook energy theorem

Work done = change in KE

$\\\begin{aligned}&=\frac{1}{2} m u^{2}-\frac{1}{2} m v_{i}^{2} \\&=\frac{1}{2} m\left(v_{f}^{2}-v_{i}^{2}\right) \\&=0.5 \times 15.5\left(1105-7.5^{2}\right) \\w &=[589 \mathrm{J}]\end{aligned}$$$
