A) \[\text{Yes,6}{{\text{0}}^{\text{o}}}\]
B) \[\text{Yes,}\,\text{3}{{\text{0}}^{\text{o}}}\]
C) \[\text{No}\]
D) \[\text{Yes,}\,{{45}^{\text{o}}}\]
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.
