A 2.10-g particle is released from rest at point A on the inside of a smooth hemispherical bowl of radius R = 28.0 cm.
Calculate the following:
(a) Its gravitational potential energy at A relative to
(b) Its kinetic energy at B.
(c) Its speed at B.
(d) Its potential energy at C relative to B.
(e) Its kinetic energy at C.
A figure needs to be shown or described.
So does some effort on your part. This is a conservation of energy problem.
