Question

A particle undergoes simple harmonic motion having time period t

Answer 1

:Find the time taken in (3/8)th 9 oscillation.))

______Hey....!!____

__________

Your answer:-

Time taken to complete one fourth oscillation T/ 4

so time to complete 1/8th oscillation from to extreme position is obtained from

y= a/2 = a cos cot = a cos 2 pai / T × t

0r cos Pai /3 = cos 2pai t/ T

t = (T/6) s

hence time to complete 3/8th oscillation

= T/4 + T/6

= 5T /12
