Question
In the figure, a 3.97 g ice flake is released from the edge of a hemispherical bowl whose radius ris 13.7 cm. The flake-bowl contact is
frictionless. (a) How much work is done on the flake by the gravitational force during the flake's descent to the bottom of the bowl? (b)
What is the change in the potential energy of the flake-Earth system during that descent? (c) If that
potential energy is taken to be zero at the bottom of the bowl, what is its value when the flake is released? (d) If, instead, the potential
energy is taken to be zero at the release point, what is its value when the flake reaches the bottom of the bowl?
