Two simple harmonic motions are represented by the equations
`y_(1) = 8 sin(pi)/(4)(10t + 2),y_(2) = 6(sin 5pit + sqrt(3) cos 5omegat)`
IF the ratio of amplitudes of `y_(1) and y_(2)` is `alpha` and their respective ratio of time periods is `beta`, then find `beta//alpha`.

The correct Answer is:
To solve the problem, we need to find the ratio of amplitudes (α) and the ratio of time periods (β) of the two simple harmonic motions given by the equations: 1. \( y_1 = 8 \sin\left(\frac{\pi}{4}(10t + 2)\right) \) 2. \( y_2 = 6\left(\sin(5\pi t) + \sqrt{3} \cos(5\pi t)\right) \) ### Step 1: Identify the Amplitudes From the equation of \( y_1 \): - The amplitude \( A_1 = 8 \). For \( y_2 \), we need to rewrite it in the standard form \( A \sin(\omega t + \phi) \): - We can express \( y_2 \) as: \[ y_2 = 6\left(\sin(5\pi t) + \sqrt{3} \cos(5\pi t)\right) \] Using the formula \( R = \sqrt{a^2 + b^2} \) where \( a = 6 \) and \( b = 6\sqrt{3} \), we can find the amplitude: \[ R = 6\sqrt{1^2 + \left(\sqrt{3}\right)^2} = 6\sqrt{1 + 3} = 6\sqrt{4} = 12 \] Thus, the amplitude \( A_2 = 12 \). ### Step 2: Calculate the Ratio of Amplitudes (α) Now we can find the ratio of the amplitudes: \[ \alpha = \frac{A_1}{A_2} = \frac{8}{12} = \frac{2}{3} \] ### Step 3: Identify the Angular Frequencies and Time Periods Next, we need to find the time periods of both motions. For \( y_1 \): - The angular frequency \( \omega_1 \) can be found from the equation: \[ \frac{\pi}{4} \cdot 10 = \omega_1 \implies \omega_1 = \frac{10\pi}{4} = \frac{5\pi}{2} \] - The time period \( T_1 \) is given by: \[ T_1 = \frac{2\pi}{\omega_1} = \frac{2\pi}{\frac{5\pi}{2}} = \frac{4}{5} \] For \( y_2 \): - The angular frequency \( \omega_2 = 5\pi \). - The time period \( T_2 \) is given by: \[ T_2 = \frac{2\pi}{\omega_2} = \frac{2\pi}{5\pi} = \frac{2}{5} \] ### Step 4: Calculate the Ratio of Time Periods (β) Now we can find the ratio of the time periods: \[ \beta = \frac{T_1}{T_2} = \frac{\frac{4}{5}}{\frac{2}{5}} = \frac{4}{2} = 2 \] ### Step 5: Calculate the Ratio β/α Finally, we need to find the ratio \( \frac{\beta}{\alpha} \): \[ \frac{\beta}{\alpha} = \frac{2}{\frac{2}{3}} = 2 \times \frac{3}{2} = 3 \] ### Final Answer Thus, the value of \( \frac{\beta}{\alpha} \) is \( 3 \). ---
