A) Yes, \[60{}^\circ \]
B) Yes,\[30{}^\circ \]
C) No
D) Yes,\[45{}^\circ \]
Correct Answer: A
Solution :
[a] Man will catch the ball if the horizontal component of velocity becomes equal to the constant speed of man i.e., |
\[{{v}_{0}}\cos \theta =\frac{{{v}_{0}}}{2}\]\[\Rightarrow \]\[\cos \theta =\frac{1}{2}\] |
\[\Rightarrow \] \[\cos \theta =\cos {{60}^{o}}\] |
\[\therefore \] \[\theta ={{60}^{o}}\] |
