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