A ball is projected from ground with velocity v with angle theta to the vertical. On its path it makes an elastic collision with a vertical wall and returns to the ground. Total time of flight of ball is.....
1. 2vsin theta/g
2. 2vcos theta/g
3. v sin theta/g
4. vcos theta/g

Dear student
 
 
as ball  returnes to the ground it make collision in horizontal direction i.e. at its max height
vertical compoent of velocity = Vcos\Theta
0 = Vcos\Theta – gt
So t = Vcos\Theta/g
Then time of flight = 2t = 2Vcos\Theta/g.
Hope it clears.
