v 3.5m 3.2m А A 1.1m 1. An ice block on a frictionless path starts at rest and is released on the path. At the top of the path, the block obviously has GPE, how much GPE does it have at point A when it starts at rest?​

Panel bc in fig. p2.76 is semi-circular, with the 3 meter radius and horizontal straight edge through point b. compute (a) the hydrostatic force of the water on the panel, (b) its center of pressure, and (c) the moment of this force about point b. assume atmospheric pressure on the dry side of the panel
