The potential energy of the 20 kg rock on the edge of a 100 m cliff is twice as much as the potential energy of the 20 kg rock on the edge of a 50 m cliff. This is because potential energy is directly proportional to the height of the object above the reference point (in this case, the ground).
Kinetic energy is energy available due to velocity, so you can exclude the compressed spring and the rock sitting on a cliff. As far as the bicycle vs the car, the car is the easy winner. EK = 0.5 m v2 Since both the mass (m) and the velocity (v) of the car exceeds that of the bicycle, it is clear that EK-Car is much greater than EK-Bicycle.
The amount of wind on a seaside cliff can vary depending on weather conditions and location, but it is typically stronger and more consistent due to the open exposure of the cliff to the ocean. Wind speeds can be significantly higher on cliffs, creating gusty conditions that can be dangerous for those near the edge.
