Two balls are projected from the same point with such a speed that both reach the same point on ground at a distance of `19.6 sqrt(3) m` from the point of projection. If one of the particles is projected at an angle of `30^(@)` with the ground, then calculate the time of flight of the second ball.

To solve the problem, we need to calculate the time of flight of the second ball that is projected at an angle of 60 degrees, given that the first ball is projected at an angle of 30 degrees and both reach the same point on the ground. ### Step-by-Step Solution: 1. **Understand the Range Formula**: The range \( R \) of a projectile is given by the formula: \[ R = \frac{u^2 \sin(2\theta)}{g} ...
