Answer:

The kinetic energy of the white car will increase, while that of the yellow car will reduce

Explanation:

According to Newton's law of motion, a body will be a rest or uniform motion unless acted upon by an external force

Since the white car is moving at 5km/h west and another car moving at 10km/h west the kinetic energy possessed by the white car will increase because the other car is moving along the Same direction with it

The expression kinetic energy is

KE= 1/2mv²
