The correct Answer is:
To solve the problem step by step, we need to find the acceleration of the combined mass when both masses \( m_1 \) and \( m_2 \) are tied together and subjected to a force of \( 5N \). ### Step 1: Determine the mass \( m_1 \) We know that the force \( F \) acting on mass \( m_1 \) produces an acceleration of \( 8 m/s^2 \). According to Newton's second law, we can write: \[ F = m_1 \cdot a_1 \] Substituting the known values: \[ 5N = m_1 \cdot 8 m/s^2 \] Now, we can solve for \( m_1 \): \[ m_1 = \frac{5N}{8 m/s^2} = \frac{5}{8} \text{ kg} \] ### Step 2: Determine the mass \( m_2 \) Similarly, for mass \( m_2 \) which has an acceleration of \( 24 m/s^2 \): \[ F = m_2 \cdot a_2 \] Substituting the known values: \[ 5N = m_2 \cdot 24 m/s^2 \] Now, we can solve for \( m_2 \): \[ m_2 = \frac{5N}{24 m/s^2} = \frac{5}{24} \text{ kg} \] ### Step 3: Calculate the total mass \( m_1 + m_2 \) Now that we have both masses, we can find the total mass: \[ m_1 + m_2 = \frac{5}{8} \text{ kg} + \frac{5}{24} \text{ kg} \] To add these fractions, we need a common denominator. The least common multiple of \( 8 \) and \( 24 \) is \( 24 \): \[ m_1 = \frac{5}{8} = \frac{15}{24} \text{ kg} \] Now we can add: \[ m_1 + m_2 = \frac{15}{24} + \frac{5}{24} = \frac{20}{24} = \frac{5}{6} \text{ kg} \] ### Step 4: Calculate the acceleration of the combined mass Now we can use the total mass and the force to find the acceleration when both masses are tied together: \[ F = (m_1 + m_2) \cdot a \] Substituting the known values: \[ 5N = \left(\frac{5}{6} \text{ kg}\right) \cdot a \] Solving for \( a \): \[ a = \frac{5N}{\frac{5}{6} \text{ kg}} = 5N \cdot \frac{6}{5} = 6 m/s^2 \] ### Final Answer The acceleration when both masses are tied together is: \[ \boxed{6 \, m/s^2} \]

To solve the problem step by step, we need to find the acceleration of the combined mass when both masses \( m_1 \) and \( m_2 \) are tied together and subjected to a force of \( 5N \). ### Step 1: Determine the mass \( m_1 \) We know that the force \( F \) acting on mass \( m_1 \) produces an acceleration of \( 8 m/s^2 \).
