A body is projected vertically upwatds at time t=0 and is it seen at a height H at time `t_1` and `t_2` second during its flight. The maximum height attainet is (g is acceleration due to garavity).

Options

A. `(g(t_2-t_1)^2)/8`
B. `(g(t_2+t_2)^2)/4`
C. `(g(t_1+t_2))/8`
D. `(g(t_2-t_1)^2)/4`

Explanation

According to given conditions, Group (A) does not represent the variation of K.E because initially when `y=0. K.E should also be zero which is not show in graph (A).
