If a bicycle and a delivery truck are moving down a road at the exact same speed which one has more kinetic energy

Kinetic energy is directly proportional to an object's mass and the square of its velocity ($KE = \frac{1}{2}mv^2$). Since both the bicycle and the delivery truck are moving at the same speed, the object with the greater mass will have more kinetic energy. A delivery truck has significantly more mass than a bicycle, so it possesses more kinetic energy.
