A small block of mass m = 225 g is released from rest at point circled A along the horizontal diameter on the inside of a frictionless, hemispherical bowl of radius R = 27.5 cm as shown in the figure below.
(a) Calculate the gravitational potential energy of the block-Earth system when the block is at point circled A relative to point circled B.
(b) Calculate the kinetic energy of the block at point circled B.

(c) Calculate its speed at point circled B.
m/s
(d) Calculate its kinetic energy when the block is at point circled C.
J
(e) Calculate the potential energy when the block is at point circled C.
