Starting from the mean position a body oscillates simple harmonically with a period of 2 s . Its kinetic energy will become $75%$ of the total energy after :

Options:

Answer:

Solution:

Ans. (A) $v = A ω cos (ω t)$ for $KE = 75%$ of $KE_{max}$ $v = \frac{3}{2}$ of $v_{max}$ $\frac{3}{2} A ω = A ω cos (\frac{2 π}{2} \times t) \Rightarrow t = \frac{1}{6} sec$ .
