1.	15. A particle in S.H.M. has a velocity 20 cm/sec, when it crosses the meanposition. Find its velocity when it ismidway between the mean position andextreme position.
Answer» Maximum value of velocity is obtained at the mean position , such that :Now we need to find the velocity when the OSCILLATORY particle passes the half position between the mean and extreme positions.Velocity at any point is REPRESENTED as :We KNOW that x = A/2 as per Question :So final ANSWER :
