Question

the periodioc time of a body executing simple harmonic motion in 3 sec. after how much interval from time T=0, will its displacement be half of its amplitude?

Answer 1

Heya mate ur answer is

T= 2s, t = ? , y = ma/2

Now, y = asinwt ( here w is omega)

=asin2pie/T×t

= a/2 = asin 2pie/T×t = asinpie×t

or pie×t= pie/6 or t=1/6 sec
