a particle is projected vertically upward from a pont A on the ground . It takes t₁time to reavh a point B but it still continues to mov up . If it takes further t₂time to reach the ground from point B then the height of point B from the Ground is

1/2g (t₁+t₂)²

gt₁t₂

1/8g(t₁+t₂)²

1/2gt₁₊t₂

Time taken for the particle to reach highest point is t1+t22t1+t22

(v=u−gt)(v=u−gt)

Therefore initial velocity=u=g(t1+t2/2)=u=g(t1+t2/2)

Therefore heigh of B from ground is

h=ut+1/2h=ut+1/2at2at2

h=ut1−1/2h=ut1−1/2gt12gt12

=g(t1+t2/2)=g(t1+t2/2)t1−12t1−1/2gt21gt12

h=1/2h=1/2gt1t2
