1.	A body describes simple harmonic motion with an amplitude of 5 cm and a period of 0.2s. Find the acceleration and velocity of the body when the displacement is 5 cm.
Answer» `(A)/(3)` `(A)/(2)` `(A)/(SQRT(2))` `(A)/(2sqrt(2))` SOLUTION :POTENTIAL energy = `(1)/(2)` (Total energy) `(1)/(2)momega^(2)y^(2)=(1)/(2)((1)/(2)momega^(2)A^(2))impliesy=(A)/(sqrt(2))`
