(iii)Time of flight (T) :
It is defined as the time for which a body remains in the air.
T=td+ ta
=>\(
\frac{u}
{g}
\) +\(
\frac{u}
{g}
\)
=>2\(
\frac{u}
{g}
\)
Note: In medium having resistance td > ta
a)Time of flight T <\(
\frac{u}
{g}
\) Then the body is moving in upward direction.
b)Time of flight T >\(
\frac{u}
{g}
\) Then the body is moving in downward direction.
c)Time of flight T =\(
\frac{u}
{g}
\) Then the body is at maximum height.
