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, \[{{v}_{0}}\cos \theta =\frac{{{v}_{0}}}{2}\] \[\Rightarrow \] \[\cos \theta =\frac{1}{2}\] \[\Rightarrow \] \[\cos \theta =\cos {{60}^{o}}\] \[\therefore \] \[\theta ={{60}^{o}}\]You need to login to perform this action.
