send the question of that solution so that I can help u
it's -g as the body is moving against the gravit
it's -g as the body is moving against the gravit
topin:
now it is moving against gravity so acceleration due to gravity will be negative
is that the question or solution

given :-
v = u + at
==> v - u = at
==> 0 = 14ms^-1 - 9.8ms-2 × t
==> 0 - (-14ms^-1) = 9.8ms^-2 × t
==> 14ms^-1 = 9.8ms^-2 × t
==> 14/9.8 = t
==> 1.4285 = t
so approximately time is taken as 1.43s
hope u understood :)
