A 245 g particle is released from rest at point A inside a smooth hemispherical bowl of radius 35.0 cm, as shown in Figure 5-21.
(a) Calculate the gravitational potential energy at A relative to B.
(b) Calculate the particle's kinetic energy at B.
(c) Calculate the particle's speed at B.
(d) Calculate the kinetic energy and potential energy at C.
4 (kinetic energy)
5 (potential energy)
