Answer:1.6 kJ

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.=\frac{1}{2}mv^2

K.E.=\frac{1}{2}\times 200\times (4)^2

K.E.=100\times 16

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