A body dropped gently from a height h takes time t to reach the ground. Velocity of this body at theheight h/2 is:A) gtB) gt/2C) gt/√2D) gt/4E) gt^2/2​

Answer»

\textbf{ Answer }

a) GT

\\

Solution :-

In solving a numerical physics, please dont be CRAZY in FINDING the answers only, The more you FEEL ,the more you know Physics.

\text{ Here,.  }

As the ball is dropped gently the it must have (u=0),

According to the equation of motion,

{ u^{2} - v^{2}}

at height H/2 , distance travelled=H/2,so

v² = 2gH/2=gH

V=√(gH )

and DIRECTION of velocity is in the direction of acceleration due to gravity.
