1The time taken by a berry to fall through the height will be calculated by h= (1/2) g t^2
In this time the soldier will travel a dist= v x t ( as calculated). Convert v into m/s before using in the eq
6seems like u r solving HCV!!!
yes he will receive it on the uniform
frm
s =ut + 1/2at^2
find t= 1.57 s
then find distance which comes out to be 2.6m..
