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