A) \[45{}^\circ \]
B) \[60{}^\circ \]
C) \[30{}^\circ \]
D) \[75{}^\circ \]
Correct Answer: A
Solution :
[a] From graph, \[{{u}_{y}}=10m/s\] \[{{\text{v}}_{y}}\] becomes zero when \[x=\frac{Range}{2}\] \[\therefore \] Range \[=20\text{ }m\] \[\therefore \,\,\,\,\,\frac{2{{u}_{x}}{{u}_{y}}}{g}=20\]You need to login to perform this action.
