- You find an interesting looking ball but can't tell if it's solid or hollow, so you design an experiment: The mystery ball is rolled along a horizontal surface with an initial translational speed of v= 2.7 m/s. Then the ball rolls up an incline and eventually stops after climbing up a vertical distance of h = 0.52 m, as shown in the figure. Based on your experiment, is the ball solid or hollow? Use calculations to support your answer. Assume the ball rolls without slipping. Note: you do not need to know the mass or radius of the ball to answer this problem. 1フA turntable 46.0 cm in diameter diameter starts from rest, and rotates at 68.0 rpm at its first complete revoļution with constant angular acceleration.
