Water is flowing at a speed of $\displaystyle 1.5 \mathrm{~ms}^{-1}$ through a horizontal tube of cross-sectional area $\displaystyle 10^{-2} \mathrm{~m}^2$ and you are trying to stop the flow by your palm. Assuming that the water stops immediately after hitting the palm, the minimum force that you must exert should be (density of water $\displaystyle =10^3 \mathrm{kgm}^{-3}$ ).
