To solve the problem, we will analyze the forces acting on each block and apply Newton's second law. Here are the steps to find the acceleration of the blocks and the tension in the string. ### Step 1: Identify the forces acting on each block 1. **For Block 1 (mass = 30 kg, inclined at 60°)**: - Weight (mg) acting downward: \( W_1 = 30 \times g = 30 \times 10 = 300 \, \text{N} \) - The component of weight acting down the incline: \( W_{1x} = W_1 \sin(60°) = 300 \sin(60°) = 300 \times \frac{\sqrt{3}}{2} = 150\sqrt{3} \, \text{N} \) - Tension (T) acting up the incline. ...
