Answer:

GIVEN,

        MASS, m                    = 1500 kg

        INITIAL VELOCITY,u  = 36 km/h = 36*5/18 = 10 m/s

        FINAL VELOCITY ,v   = 72 km/h =  72*5/18=  20 m/s

         FORMULA :

                 CHANGE IN MOMENTUM,p = mv - mu

                               1500*20 - 1500*10

                                30000 - 15000

                                  = 15000 kg m/s
