A rotating door is made from four rectangular glass panes, as shown in the figure. The mass of each pane is 94.3 kg. A person pushes on the outer edge of one pane with a force of F = 91.2 N that is directed perpendicular to the pane. Determine the magnitude of the door's angular acceleration. 1.2 m 1.2 m Number i Units

Question
A bowling ball encounters a 0.760-m vertical rise on the way back to the ball rack, as the drawing illustrates. Ignore frictional losses and assume that the mass of the ball is distributed uniformly. The translational speed of the ball is 9.08 m/s at the bottom of the rise. Find the translational speed at the top.
