Answer:1.6 kJ

Step-by-step explanation:

Given

mass of truck
$m=200\ kg$

speed of truck
$v=4\ m/s$

We know kinetic Energy is the energy possessed by a moving body such that its value is given by product of mass and square of speed.

K.E.=(1)/(2)mv^2

K.E.=(1)/(2)* 200* (4)^2

K.E.=100* 16

$K.E.=1600\ J\approx 1.6\ kJ$
