The equation below describes a physical situation: Which description best fits the equation? A) A 1.70 kg block slows down while sliding down a frictionless plane inclined at a 30° angle. B) A 1.70 kg block slows down while sliding down a plane with μ_k = 0.320, with the plane inclined at a 30° angle. C) A 1.70 kg block speeds up while sliding up a frictionless plane inclined at a 30° angle. D) A 1.70 kg block speeds up while sliding down a plane with μ_k = 0.320, with the plane inclined at a 30° angle. E) A 1.70 kg block slides over the top of an inclined plane and then descends on the other side. Both planes, inclined at a 30° angle, have μ_k = 0.320.
