    Answer:

    K.E of truck > K.E of car

    Explanation:

    Mass of the truck = 8000Kg

    K.E=\frac{1}{2} mv

    K.E =\frac{1}{2}*8000*v\\ 4000v

    Mass of the car = 1000 Kg

    K.E of the car =\frac{1}{2}*1000*v\\ 500v

    Therefore Kinetic energy of the truck is greater than that of the car
