Halliday, Resnick & Walker — Potential Energy and Conservation of Energy: Problem 11_E

(a) In Problem 5, what is the speed of the flake when it reaches the bottom of the bowl? (b) If we substituted a second flake with twice the mass, would what its speed be? (c) If, instead, we gave the flake an initial downward speed along the bowl, would the answer to (a) increase, decrease, or remain the same? (Note: Problem 5 describes a 2.00 g ice flake released from the edge of a hemispherical bowl whose radius r is 22.0 cm. The flake–bowl contact is frictionless.)
