Answer:

The bicycle will have the lowest kinetic energy

Step-by-step explanation:

Kinetic energy is given by the relationship:

KE = (1/2)mv^2

v, the velocity, is the same for all four vehicles.

However, they differ in their mass, m. Although we are not told, we can assume that the masses, in order of increasing mass, are:

Lowest: Bicycle

Motorcycle

Car, and then

Highest: Truck.

Since v is the same. the vehicle with lowest mass, m, would have the lowest kinetic energy.

The bicycle will have the lowest kinetic energy of the four vehicles.
