SUMMARY
The discussion focuses on calculating the acceleration of a block pushed up a frictionless incline at a 30-degree angle with an applied force of 50 N and a mass of 3 kg. The correct acceleration is determined to be 11.77 m/s², derived from applying Newton's second law to the forces acting on the block. Key steps include resolving forces into components parallel and perpendicular to the incline and utilizing a free body diagram for clarity. The solution emphasizes the importance of considering gravitational force components in the calculations.
