On a banked race track, the smallest circular path on which cars can move has a radius of 102 m, while the largest has a radius 157 m, as the drawing illustrates. The height of the outer wall is 18 m. Find the smallest and largest speed the cars can remove without the presence of friction.
The lower weight is a light bag filled with sand. Assume a pin pokes a hole in the bag and the sand slowly leaks out while the puck is revolving. What would be the puck's speed after all of the sand is gone.
An object consists of a ball of weight W glued to the end of a uniform bar also of weight W. if you release it from rest, with the bar horizontal.
