Answer:

A. The bus has more kinetic energy than the car.

Explanation:

Kinetic energy is the amount energy possessed by the body when in motion. Kinetic is given by the formula;

K.E = 1/2mv²,

where m is the mass of the body and v is the velocity of the body.

Kinetic energy therefore depends on the mass and the velocity of the body. In this case, the passenger bus has more kinetic energy at constant speed than the car since it has a larger mass.
