A projectile is fired vertically upwards...

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

A

They meet at time t` = u/g ` and at a height `(u^2)/(2g) + (gT^2)/(8)`

B

They meet at time t` = u/g +T/2 ` and at a height `(u^2)/(2g) - (gT^2)/(8)`

C

They meet at time t` = u/g +T/2 ` and at a height `(u^2)/(2g) + (gT^2)/(8)`

D

They never meet
