SUMMARY
The discussion focuses on calculating the acceleration and speed of a 4 kg block released from rest on a frictionless inclined plane at a 30-degree angle. The solution involves applying Newton's second law (F = ma) to determine the component of gravitational force acting down the slope, resulting in an acceleration of approximately 5.3 m/s². Subsequently, using the equation of motion v² = u² + 2as, the speed of the block after moving 3 meters is calculated to be approximately 7.75 m/s.
