27 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 P on the wall at a height 5 m from the ground It is observed that this can be achieved with two different angles of projection and If the time taken by the projectile to hit the point P when projected at angles and is and respectively and then g 10m s Choose 1 U 14 0 45 0 4 2 s 5 s t tan 15 m 2 4 5 m
