Question 2 (12 points) A solid sphere (mass of m, radius of r, and / = = mr?) is rolling without slipping on a rough surface with a speed of v. A ramp (mass of 2m and angle of ) rests on a smooth surface that is located on Earth, as shown in the diagram. In Trial 1, the ramp is free to slide on the surface whereas in Trial 2, it is fixed to the surface so that it cannot move. O rough rough smooth (a) Indicate whether the height of the sphere relative to the ground when the sphere reaches the top of the ramp is greater in Trial 1 or Trial 2. Qualitatively justify your answer in a clear, coherent paragraph- length explanation. w AP* Physics 1: Rotation and Angular Momentum (b) Quantitatively justify your answer to Part (a). Provide the height, h, in both Trial 1 and Trial 2 in terms of the given variables and any fundamental constants
