w2hen the angle of projection is larger than 45 degree the height attained will be more but the range is again less.in this case angle is 30 degree which is less than 45 degree and 60 degree angle is greater than angle of 45 degree which have less range and is equal to range of 30 degree .so ranges are equal.
The range of a projectile depends on its initial velocity and launch angle. In this case, both rubber pipes are projecting water at the same speed, so they have the same initial velocity. The range of a projectile launched at 30 degrees and 60 degrees with the same initial velocity will be equal due to the symmetrical nature of projectile motion. The horizontal component of the velocity is the same for both angles, resulting in equal ranges.
