In this problem, the block moves in the horizontal direction only. ### Diagram: - A block is depicted, and an arrow represents a force \( F = 40 \, \text{N} \) applied at a 30-degree angle to the horizontal. ### Instructions: **A.** Find the work done if the force is applied for a distance of \( d = 2 \, \text{m} \). **B.** If the mass is \( m = 6 \, \text{kg} \) and the initial velocity is \( V_i = 0 \), use the work-energy theorem to find the final velocity. **C.** If the process in part (B) took a time of \( t = 0.8 \, \text{s} \), use your answer from part (B) to calculate the acceleration of the block. **D.** Now use Newton’s second law (in the x-direction) to calculate the acceleration. Your answers from Part (C) and (D) should be pretty close. They're different because of rounding errors.
