Which object has the least amount of kinetic energy?
a car driving down a road
a soccer ball rolling down a hill
a bicycle locked to a bike rack
a satellite orbiting earth

The correct answer is "a bicycle locked to a bike rack".

Explanation:

The kinetic energy is due to the motion of the object.

The expression of the kinetic energy is as follows:

Here, m is the mass of the object and v is the speed of the object.

In the option, a car driving down a road, the car has a kinetic energy due to the motion of the car.

In the option, a soccer ball rolling down a hill , the soccer ball has a kinetic energy due to the motion of the soccer ball.

In the option, a bicycle locked to a bike rack, the kinetic energy of a bicycle is zero as the bicycle is locked. It is not moving.

In the option, a satellite orbiting Earth, the satellite has a kinetic energy as it is orbiting the earth.

Therefore, the correct option is "a bicycle locked to a bike rack".
