Figure 1. Blocks \(m_B\) (upper) and \(m_A\) (lower) connected by a cord on an incline of angle \(\theta\).
Two blocks made of different materials, connected by a thin cord, slide down a plane ramp inclined at an angle \(\theta = 32^\circ\) above the horizontal. If the coefficients of friction are \(\mu_A = 0.2\) and \(\mu_B = 0.3\) and if \(m_A = m_B = 5.0\,\text{kg}\), determine:
