A particle is projected from the ground towards a fixed vertical wall with an initial velocity 15 m s The foot of the wall is at a distance 15 m from the point of projection It is desired that the particle hits a point Pon the wall at a height 5 m from the ground It is observed that this can be achieved with two different angles of projection 0 and 0 If the time taken by the projectile to hit the point P when projected at angles 0 and 0 is and respectively and then g 10 m s 2 8 45 08 tan 2 4 2 s 0 12 5 s 15 m O 5m
