If we throw a body upwards with velocity of 
at what height its kinetic energy reduces to half of the initial value? Take 
Text Solution
Verified by ExpertsThe correct answer is:
D
: We know kinetic energy 
∴ ∴ 
When kinetic energy of the body reduces to half its velocity becomes v = 
From the equation 
⇒ ⇒ 
∴ ∴ 
.
