Identify the equation that DOES NOT represent oscillatory motion. ( A is amplitude of motion)
Options
- Ay = A t + A 2 t
- Bx = A ( t - 4 )
- Cy = A t + A ( t + /2)
- Dy = A ( t - 4 )
Correct answer
C. y = A t + A ( t + /2)
Step-by-step solution
Let us analyze each option to determine if it represents oscillatory motion. For the equation y = A t + A 2 t , the motion is a superposition of two harmonic functions with commensurable frequencies. This represents a periodic and oscillatory motion. For the equation x = A ( t - 4 ) , the motion is simple harmonic, which is inherently oscillatory. For the equation y = A t + A ( t + /2) , we can simplify it using the trigonometric identity ( + /2) = - : y = A t - A t = 0 Since the displacement y is zero for all time
