As we discussed in Concept

2nd equation or Position- time equation -

s= ut +\frac{1}{2}at^{2}

s\rightarrow Displacement

u\rightarrowInitial velocity

a\rightarrowacceleration

t\rightarrow time

 

-

 

 

 h=ut+\frac{1}{2}gt^{2}

l=\sqrt{\frac{2h}{g}}

Since no other force are meting in vaccum time of decent will be exactly equal
