Answer 2

Answer:

answer is 4000000J

Explanation:

mass given 5 metric tons so the actual mass of the body is 5000kg as 1 metric ton =1000kg

speed given 144km/hr

therefore the actual speed of the body in m/s =144x 1000m/60x60 s =40m/s

therefore the kinetic energy =1/2 x 5000kg x 40 x 40 m/s=4000000J
