Unformatted text preview: homework 32 HETTIGER, CHRISTOF Due: Apr 17 2008, 4:00 am 1 Question 1, chap 15, sect 2. part 1 of 1 10 points Simple harmonic motion can be described using the equation y = A sin( k x- t- ) . Hint: sin(- ) =- sin . Consider the simple harmonic motion given by the figure. + A-A y 2 3 4 At position x = 0, we have t This motion is described by 1. y = A sin parenleftbigg- t + 3 2 parenrightbigg correct 2. y = A cos parenleftBig- t + 2 parenrightBig 3. y = A cos parenleftbigg- t- 3 2 parenrightbigg 4. y = A tan parenleftbigg- t + 3 2 parenrightbigg 5. y = A sin parenleftbigg- t- 3 2 parenrightbigg 6. y = A tan parenleftbigg- t- 3 2 parenrightbigg 7. y = A tan parenleftBig- t + 2 parenrightBig 8. y = A cos parenleftbigg- t + 3 2 parenrightbigg 9. y = A sin parenleftBig- t + 2 parenrightBig Explanation: If the y-axis 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 x-axis. Its displacement varies with time according to the equation, x ( t ) = A sin( t + ) ....
