here is your answer
given :
mass = 1500 kg
initial velocity (u) = 36 km/hr = 36*(5/18) = 10 m/s
final velocity (v) = 72 km/hr = 72*(5/18) = 20 m/s
solution :
change in momentum = final momentum - initial momentum
change in momentum = mv-mu
change in momentum = m(v-u)
change in momentum = 1500(20-10)
change in momentum = 15000 kgm/s
