In the development of the model for the force of a jet on a target $($Lab $5),$ you assumed that both gravity and viscous$/$shear forces could be ignored to arrive at the force expression

$F=A_j{v}^2(1-cos)$

A comparison of the measured force $(F_{\text{m}\text{e}\text{a}\text{s}})$ and the predicted force $(F_{\text{p}\text{r}\text{e}\text{d}})$ of a jet on the target with $=30$ is shown in the figure below. Note that if the measured and predicted values were the same, the plot symbols would all fall on the $45($solid$)$ line on the plot. Clearly$*$ the measured force values are above the predicted values.

Revisit the development of the jet$-$force model given above. Could including either gravity or dra$\frac{g}{s}$hear forces account for the observed difference between what the current model predicts and what was measured in the lab? Explain your reasoning being clear about how the neglected forces might impact the measurement.
