The statement is an opinion because it expresses a preference of an individual than an actual fact.
The BUS will have the highest kinetic energy, while the BICYCLE will have the lowest kinetic energy.
This is because if an object has a greater mass, the kinetic energy of the object also increases. Kinetic energy depends on mass and velocity (KE=1/2*m*v^2) and since the velocity of these vehicles are the same, the mass is the only difference
