Q2. A ball projected from ground at an angle of 45β just clears a wall in front. If point of projection is 4 m from the foot of wall and ball strikes the ground at a distance of 6 m on the other side of the wall, the height of the wall is : (1) 4.4 m (2) 2.4 m (3) 3.6 m (4) 1.6 m
What This Question Tests
This question is a direct application of the equation of trajectory for a projectile launched from the ground, requiring substitution of given values to find the height at a specific horizontal distance.
