Question

Even after the collision there will be no change in the time period of flight as in an elastic collision the ball will bounce with same angle as angle

Vedclass · Accepted Answer

$\frac{{2v\cos 	heta }}{g}$

Vedclass · Answer

Even after the collision there will be no change in the time period of flight as in an elastic collision the ball will bounce with same angle as angle of incident and with same velocity as incident velocity so the trajectory will be just like mirror image of original trajectory about the wall.

so time of flight will remain unchanged i.e., $\frac{2 v \cos 	heta}{g}$

$A$ ball is projected from ground with a velocity $V$ at an angle $\theta$ to the vertical. On its path it makes an elastic collison with $a$ vertical wall and returns to ground. The total time of flight of the ball is
