Hint: sin( ) = sin . Consider the simple harmonic motion given by the figure. + AA y 2 3 4 At position x = 0, we have t This motion is described by 1. y = A tan parenleftBig t + 2 parenrightBig 2. y = A sin parenleftbigg t + 3 2 parenrightbigg correct 3. y = A cos parenleftbigg t 3 2 parenrightbigg 4. y = A sin parenleftbigg t 3 2 parenrightbigg 5. y = A tan parenleftbigg t + 3 2 parenrightbigg 6. y = A cos parenleftBig t + 2 parenrightBig 7. y = A cos parenleftbigg t + 3 2 parenrightbigg 8. y = A tan parenleftbigg t 3 2 parenrightbigg 9. y = A sin parenleftBig t + 2 parenrightBig Explanation: If the yaxis is moved such that the angle t + 3 2 = 0 , the curve is the sine function A sin( t ) ; therefore y = A sin parenleftbigg t + 3 2 parenrightbigg is the curve in the figure. Question 2, chap 15, sect 2. part 1 of 1 0 points A body oscillates with simple harmonic mo tion along the xaxis. Its displacement varies with time according to the equation, x ( t ) = A sin( t + ) ....
