The cube is released, it collides and STICKS to a 2.0 kg sphere initielly at rest on the edge of a table 2.0 meters from the ground. The Sphere & Cube hit the floor at a distonce D from the edge of the table. a) Calculate the speed of the cube just BEFORE the collision. Your answer b) Calculate the speed of the cube & Sphere immediately AFTER the colision. Your answer c) Calculate the final speed landing) of the cube & Sphere. (HINT: Conservation of Energy). Your answer d) Determine the total distance (D) where the objects landed together.
