Question

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

Answer 1

$\textbf{ Answer }$

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.
