kinetic & potential
B.
No kinetic energy
no kinetic energy

B and then to C?
(1) The potential energy at A, B and C are the same. X
(2) Potential energy was the highest at A and was lost at B. X
(3) Kinetic energy increased from A to B and again from B to C.
(4) Kinetic energy increased from A to B and decreased from B to C.
