1.	Simple harmonic motion is represented by the equation x = 4 sin(2pi t+pi//4) metre. What is the initial displacement?
Answer» Solution :Given x = 4 `SIN (2PI t + pi/t)` to CALCULATE initial displacement put t=0 in the given equation. `therefore x = 4 sin (0 + pi/4) = 4 sin 45^@ = 4 1/(sqrt(2)) = 2SQRT2 ` metre.
