Two towers $AB$ and$CD$ are situated a distance $d$apart as shown in fig. . $AB$ is $20 m$ high and$CD$ is $30 m$ high from the ground. An object of mass $m$ is thrown from the top of $AB$ horizontally with a velocity of $10 m/s$ towards $CD.$ Simultaneously another object of mass $2 m$ is thrown from the top of $CD$ at an angle of ${60}^{°}$ to the horizontal towards $AB$ with the same magnitude of initial velocity as that of the first object. The two objects move in the same vertical plane, collide in mid-air and stick to each other
Find the position where the objects hit the ground. $(g = 9.8 m/s^2)$
