5. A car travels at constant speed v up a hill from point A to point B, as shown in the diagram below.
A
EV
Horizontal
B
As the car travels from A to B, its gravitational potential energy (1) increases and its kinetic energy
decreases (2) increases and its kinetic energy remains the same (3) remains the same and its kinetic
energy decreases (4) remains the same and its kinetic energy remains the same
