the gravitional force will always reamin constant throughout the fall.so they told to take the vertically force upwards.so accleration is negative

here you go
thanx soo much:) just a few doubts:
in qn 1.) why do they do S2X-S1X ??
and this (n+1/2)lambda and n x lambda........are they formulas we need to know?? and what exactly is 'n'?
qn 2.) when i do (3/100 x 327.66) i get 98.3 while u have written 10
thanx again:)

yes those are formula n is like a constant and its integers like 0,1,2,3,4,5,6,7.......
and it come 9.83 you rounded to 1 sf equal to 10
