Question

Distange by ( underline{n} ) th second
[
begin{array}{l}
S_{n}=u+frac{a}{2}(2 n-1) quadleft[tan n=frac{u}{g} omega_{n}right]
S_{n}=u+frac{-g}{2}left(frac{2 u}{g}-1right) quad a=-g
=u+left[-u+frac{g}{2}right)
S_{n}=g / 2
end{array}
]
last second distance covend is ( 8 / 2^{m} )

# O cd body is projusted with some goed from ground vertically reprore. Eind the distance travelled by the body in last seconds of its pard journey.
