If you can please explain your answer so I can fully understand. Thank you so much!Show me the steps to solve 13. Consider a solid cylinder of mass and radius sliding without rolling down the smooth inclined face of a wedge of mass that is free to slide without friction on a horizontal plane floor. Use the coordinates shown in the figure. a. How far has the wedge moved by the time the cylinder has descended from rest a vertical distance ? b. Now suppose that the cylinder is free to roll down the wedge without slipping. How far does the wedge move in this case if the cylinder rolls down a vertical distance ? c. In which case does the cylinder reach the bottom faster? How does this depend on the radius of the cylinder?

The angle between the ball's initial velocity vector and the wall is 6 as shown on the diagram, which depicts the situation as seen from above. The duration of the collision between the ball and the wall is At, and this collision is completely elastic. Friction is negligible, so the ball does not start spinning. In this idealized collision, the force exerted on the ball by the wall is parallel to the x axis. What is the final angle Or that the ball's velocity vector makes with the negative y axis?
