Answer»

mass of truck= 1000 kg

initial speed of truck= 36 km/h= 10 m/s

FINAL speed of truck= 72 km/h= 20 m/s

Initial KINETIC energy of truck= 1/2 *1000*10*10

                                               = 50000 J

Final kinetic energy of truck= 1/2 *1000*20*20

                                              = 200000 J

Increase in the kinetic energy of truck= final K.E. - initial K.E.

                                                               = 200000-50000

                                                               = 150000 J
