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

Question

Arun · Answer

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 0 = Vcos – gt So t = Vcos /g Then time of flight = 2t = 2Vcos /g. Hope it clears. Regards Arun (askIITians forum expert)
