Quizplus · Accepted Answer

When the rope breaks, the only force acting on the rock along the inclined plane is the component of gravity. The acceleration of the rock is given by g*sin(θ), where g = 9.8 m/s². Assuming the incline angle θ is such that sin(θ) = 0.5, the acceleration would be 9.8 * 0.5 = 4.9 m/s².
