Question

A body is falling from a height h. After it has fallen a height `(h)/(2),` it will possess :
A. only potential energy
B. only kinetic energy
C. half potential and half kinetic energy
D. more kinetic and less potential energy

Answer 1

Correct Answer - C
At a height h, PE = mgh At a height `h//2, PE = mg ((h)/(2)) = (1)/(2)mgh` The rest `((1)/(2) mgh)` of the PE is converted into KE. Thus, at a height `(h//2), PE = KE = (1)/(2)mgh.`
