Question : A projectile is fired vertically upwards with an initial velocity ๐‘ข. After an interval of T seconds a second projectile is fired vertically upwards, also with initial velocity is

(A) They meet at time t=\dfrac{u}{g} and at a height \dfrac{u^{2}}{2G}+\dfrac{gT^{2}}{8}

(B) They meet at time t=\dfrac{u}{g}+\dfrac{T}{2} and at a height \dfrac{u^{2}}{2g}+\dfrac{gT^{2}}{8}

(C) They meet at time t=\dfrac{u}{g}+\dfrac{T}{2} and at a height \dfrac{u^{2}}{2g}-\dfrac{gT^{2}}{8}

(D) They never meet

Answer : option (C)

Solution :

A projectile is fired vertically upwards with an initial velocity ๐‘ข. After an interval of T seconds a second projectile is fired vertically upwards, also with initial velocity is
