A 278 g particle is released from rest at point A inside an smooth hemispherical bowl of radius 36.5 cm, as shown below.

(a) Calculate the gravitational potential energy at A relative to B.
J
(b) Calculate the particle's kinetic energy at B.
J
(c) Calculate the particle's speed at B.
m/s
(d) Calculate the potential energy and kinetic energy at C.
PE = J
KE = J
