Two stones A and B are projected from the same point. B is thrown 1 second after A is thrown. A is projected with a velocity of 60 m/s at an angle 30∘ with the horizontal and B is projected with velocity u at an angle of 45∘ with the horizontal. Find u if both stones hit the ground at the same time. (Take g=10 m/s)

1.	Two stones A and B are projected from the same point. B is thrown 1 second after A is thrown. A is projected with a velocity of 60 m/s at an angle 30∘ with the horizontal and B is projected with velocity u at an angle of 45∘ with the horizontal. Find u if both stones hit the ground at the same time. (Take g=10 m/s)
Answer» Two stones $A$ and $B$ are projected from the same point. $B$ is thrown $1$ second after $A$ is thrown. $A$ is projected with a velocity of $60 m / s$ at an angle $30^{\circ}$ with the horizontal and $B$ is projected with velocity $u$ at an angle of $45^{\circ}$ with the horizontal. Find $u$ if both stones hit the ground at the same time. (Take $g = 10 m / s$ )
