A ball is released from the bottom of an elevator which is traveling upward with a velocity of 6 ft/s. If the ball strikes the bottom of the elevator shaft in 3 s, determine the height of the elevator from the bottom of the shaft at the instant the ball is released. Also, find the velocity of the ball when it strikes the bottom of the shaft.

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?

Please solve be integrating, draw out all free body diagrams, and show any formulas used, thanks!

I need help with FBD of this problem Please Draw clearly
